Anmyone put a Westers or Hypertec in their 8.1 / Allison? I have a 2004 2500HD CC and 285's. Need to recalibrate for the larger tires and wondering if Westers or Hypertec will give me better MPG?

 

Thanks, D.

I have a Westers in mine and it really helped alot. I have a 2003 2500HD 8.1/Ally. I just got the 265 BFG's and got Lyndon to recalibrate for them. I would definately go with Westers over a handheld unit.

I had a superchips, then switched to westers. It really woke the truck up, and it shifts real nice now. IMO I don't think handheld tunes can compare to a custom tune, once you get it right. Spend the extra money and go with a custom tune.

I told him to take some TM out, but to keep it somewhat safe. I can still feel it somewhat but not to much....as far as MPG, I got the 93 tune so I lost some...probably somewhere between 1.5-2 mpg. But then again, sometimes it makes me stomp it a little at stoplights......I enjoy driving my truck...that's all that matters

I have a 3/4 ton full size extended cab with a 496c.i. BigBlock, 5 speed Ally and 4:10 gears . . . . . .MPG was not even a consideration when i purchased it...:lol:. I also opted for the 93 "hot tune" from westers, so i probably lost a MPG or two with my tune. He does have dual tunes and tunes just for recouping some MPGs if you are really concerned with it, but we are dealing with big trucks with big power.

Also, i told Lyndon to remove as much T/M as he felt comfortable doing and that would be fine with me. I may call him back to remove more because of how nice it feels just from whats gone already. I think removing to much T/M with the ALLY transmision can cause erratic shifting patterns.

IF those are the only choices get the westers. If you have a laptop and like to play around with the tuning yourself look into hp tuners. You can do anything westers does. Make some changes, test run, make more changes, etc. It cost about what a westers costs (500).

I'm getting 9-9.5 around town, but that's averaging 22-25 mph for a tank of gas. Highway I'm getting 11-11.5. I know my trip computer / odometer are off because I have 285's and haven't re-programmed. I did a highway trip and used GPS to get miles traveled. Got 13.5 highway traveling 80 MPH. Pretty d**n good for a Big Block.

 

I don't mind the torque management. I did like the way my 1500's shifted when in tow-haul mode.

 

I'll probably go with Westers. Nice thing about Hypertec for the 2004's is one works for all models (1500-2500-2500HD-3500). So if I ever got sick of it I could sell on e-bay. I still go back and forth.

But the even nicer thing with Wester's tune is the 100% credit of what you paid toward the tune for your NEXT truck. Hypertech only works on one year, Wester's works on every year!!! :lol:

 

 

 

if your next truck is an lly duramax you will have to wait to apply that 100% credit. i have been waiting since may for lyndon to work up a tune for the new duramax but he is busy with another project. hope he finds time soon. the credit is like money in the bank that you can't touch.

sorry have to disagree. tts has a program for the lly, its been out well over a month. i think lyndon is busy with some other project. i sent westers garage an e-mail and the response was they could get me an edge at lyndons cost. huh? not what i was hoping to hear. this is not a bash but patience is not one of my strong points. i want to feel the power of the tune again. ray

Yes, that is a tough one. No one has broken the code for the LLY's yet! I bet Lyndon will be first though!

 

 

 

 

 

Yep, several tuners have a mod / tune for the LLY. Edge, Bullydog, and Quadzilla all have them.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
