What else have you done to the truck? Most 6.2's put down 320-340. Even bolt ons and custom tune will have a hard time getting to 400 no? Best of luck, let us know how it works out.

E85 conversion might get him there.

 

I've gain 60hp 70tq on my 5.3 with e85 and headers basically.

did you use factory gaskets on your install or a set or aftermarket ones? Do you get a pronounced ticking in the cabin under load?

I used a new set of factory gaskets.

 

I don't recall a noise like that, I know I can hear some header pinging, but nothing crazy.

Clearly no loss of tq on his chart. If anything he gained a few HP down low. This is what i have been telling people but some refuse to listen even with charts. Different engines respond differently to headers. Once you remove the stock manifolds and see how restricrive they reallllyyy are it all makes sence.

 

Hopefully i can get mine on a dyno soon. Tuner and i are aiming for 400 to the wheels all motor..... WITH 33s

6.2 is only about 60ish or so more HP then a 5.3.... Plus we have done head work already and have a couple of custom grind cams...

 

Also on E85, no reason a 5.3 cant make 400 to the wheels N/A..... Its already been done.

 

You 6.2L guys need to quit thinking that your engines are made by gods and forged by the hammer of Thor lol

Excuse me if I didn't sift through everything to find what mods you had done. I was under the impression you had a 6.2 and were Doin bolt ons like I did. I know on e85 the 5.3s run like raped apes. My buddy has one. Figured I'd share what I had done.

Oh by all means please do!! This forum needs more sharing of all we do to see what works and what doest!!

 

When we put mine on the dyno i will post the cam specs and the charts to see what these trucks like. [emoji1]

 

So far i have an Airaid CAI, ported and polished heads port matched to 1 7/8" catless American Racing Headers, full 3" exhaust with a magnaflow 22" muffler, tuned on E85/91 by spikes performance in south texas.

 

Parts at home include set of 4.10s front and rear and a corvette LT1 intake setup with a 6.2L TB

 

Already have a turbo kit mocked up as well but want to see what i can do all motor first.

Turbos are fun....I will say that. Buddy had a turbo'd rcsb that ran 10s until a light pole got in the way...Sounds like you'll be over 500hp no problem!

Headers on a truck that you dont want to race and use for daily commuting and towing is pointless. All your gains from headers are up top 4k+ and you gain horsepower not torque. The exhaust manifolds are designed to produce low end torque for towing in truck applications, not high rpm horse power. Not to mention your truck will be loud as hell and annoy you towing on the interstate. If i had a 2wd sport truck and went to the track or the street i would run headers. A commuter and a tower? No way in hell, but to each his own. There is a video of a blue 6.2 all terrain on youtube with kooks and borla and its so loud the microphone gets distorted at idle. Check it out, sounds mean.

 

I completely disagree with your comment. I have tsp headers on my truck as well. I gained power all throughout the curve. Gains were much more pronounced in higher rpms, but still enough in lower range to justify the cost.

Anyone here that had done a muffler swap has even less of an argument. Heads actually provide some benefits...

 

I don't have before and after number on this truck...because it's a truck and I didn't see the need. Any LS platform though will see gains from longtube headers. In my CTS-V I gained nearly 35 rwhp all throughout the power band, with peak at almost 45.

If you tune for headers, especially in combination with other modifications, there are actual gains to be had. (Even for DDs...)

Was what headers alone allowed tuning to look like, though. This is a tuned pull with headers, but not adjusted for them...then tuning for the headers (we ended up making more power, this was just after one iteration...)

 

 

Allowed for more timing and a better ending AFR...

What did you dyno after the tune?

 

I'm putting my Texas Speed headers this evening and gonna take it to the dyno for a tune Sunday.

 

Cool, good luck with the install! Let me know how it goes, I'd be curious as to how close you end up to the Trans crossmember as well.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.

      I always drive in Sport mode. With more driving, I am finding the initial response when accelerating is much quicker now🖕 Lou

      Is it an optical illusion in the pic or is the truck really squatting that much horribly?

      It's Been a Long Time...

      My initial introduction was here.  It's hard to believe that I last posted in February 2013, having just deployed to Kyrgyzstan.  Since then, I've retired from the military and the 2006 Sierra SLT Z71 that first brought me to these pages was lost.  I went forward to Afghanistan in March 2013 and did a lot of sitting behind a computer on brigade staff.  Within 18 months of getting back to the States, I was selected for Drill Sergeant duty, after which I moved back to Virginia (my home state and where I served from 2004-2008).  That '06 Sierra did a lot of driving between Louisiana, Georgia, and Virginia, and ended up with nearly 320k miles by 2022.  By then, the registration had been expired for a couple of years, but the pandemic had all but eliminated tickets for such transgressions.  Admittedly too, I usually drove my wife's SUV or son's car the 2-3 times a week I had to report to work.  Teleworking sure was fun while it lasted.   I started my retirement leave four years ago and stored the Sierra at my sister's house.  A big mess was made when her fiancé passed while she was taking care of business out-of-state in late-2024, and his son pretty much mismanaged everything to do with the estate.  Even so, I was assured that my truck was safe... until it wasn't.  I found out that my truck had been scrapped about four months after the son took over everything.  There's nothing I could do; I'm 1000 miles away and it was technically abandoned property since he'd even trespassed my sister from her own house (she had no claim to it as she wasn't married, and the fiancé was the sole owner).     Anyway, today I got my second Sierra.  This is a 2010 SLE 2WB CCSB with a little over 200k miles on it.  It's got the 5.3L I'm familiar with and should handle what I need it for.  Hauling stuff that won't fit in the Transit Connect (yep, I sold out, but that's the wife's vehicle) and towing a few times a year tops.  The price seemed decent, considering how much people sell their trucks for in the Deep South: $4500.  I've seen similar trucks listed for more than double that.  I got it from a coworker who left his tag on until we transfer the title next week (Louisiana requires a notary for transfers), so I've been driving it all day.  The rear speakers don't work, which is one of the things that brought me back to these forums earlier.  I can't say how active I'll be as a poster, but I'll be scouring the archives while I find out every little thing I can about the 2010s and particular nuances/problems with my truck.   It's definitely not a GMC, but I got another Willys Jeep a few months back as well, so I'm almost at the same place I was when I first joined gm-trucks.com.  My old 1960 DJ3A was sold back around 2010 or 2011; my current Jeep is a 1946 CJ2A.  So, I've got a slightly newer GMC and a much older Jeep.  I kind of wish I still had that F-250 I had way back when too.  The Dakota is long gone and was technically my brother's truck, though I had it registered and insured.  The F-250 had to go when my grandmother's house was foreclosed on due to mismanagement around 2012 or so.     Hopefully anyone that made it this far isn't too annoyed.  I tend to be long-winded, but I'll be doing more reading than posting in the coming months.
