I think these trannys will be more then ok up to about 600hp

 

 

What gets me is the 414hp claim they have on the website... I have seen these trucks be 10hp shy of that with just bolt ons.

 

I would expect 500hp from a blown 5.3....blower cam and all....

 

A cam would be nice, just have to save up for that one. I'm pretty sure the truck can handle more but why take the chance that something catastrophic could happen. Besides before I go with more i'm gonna want to upgrade my injectors

To be fair magnacharger offers a powertrain warranty lol

 

I would buy that for sure!! I think Maggie, whipple and procharger offer powertrain warranties

There is another guy on here who went with the Hennessy Kit and he said they had his truck for over 2 months.

My schedule was so hectic after my last 6 month deployment then my company sent me to Utah for almost 3 months after only being home for 2 weeks. I didn't have the time or space in my garage and I have a friend who builds trucks/cars so I took it to him. He has a Nissan that's putting out over 830HP at the rear wheels so it was an easy decision. 12981d56011dc7636d770aba76087d42.jpgfe2cdc994aef46e759125944ebf4f301.jpg

The install doesnt seem that daunting when you look at what is involved.

I never thought about losing any boost with the headers. I'm running the stock pulley which I'm assuming is still giving me 6 psi (as per Magnuson). Guess that's something I'll have to look into a little further.

The install was done in less than a day the longest part is waiting to get the PCM back after mailing it to Magnuson.

Yikes.... They don't have a hand held? Seems like something essential to get the truck up and running atleast to some set parameters that they pre load.

 

Idk what kind of dyno my tuner has as he just got it but they didba single cab with a whipple and a 9psi pully and idk what else..... 5.3.... Remember 5.3...... 578HP/586tq to the wheels.

 

 

Good god!!! Lol

 

 

About boost loss.... Dude its probably half a psi with LTs.... Boost is pretty much backpressure so you add more flow less PSI.... But u might make more power. Only a dyno would be able to answer that.

They put a 2 day express envelop with the kit to mail out the PCM. Mine was out on Monday and back on Friday.

Do they lock out the PCM? For lets say a tuner to tune it afterwards?

Nope, which made me happy because I had already bought an Auto Cal from Black Bear. I saved the Magnuson tune and am currently running a tune from Black Bear

      OCI, not when but why?

      By Grumpy Bear · Posted

      That dog don't hunt. 😏   First, a 2025 with 12K on the clock AND idled for a year nonstop is false on it's face; this is 2026. You can do one or the other but not both.    Second, ENGINE HOURS are absolutely available. The rest is third grade math. Micky Mouse scanner he got out of a box of Cracker Jacks OR an ID10T error.    Third, if they ran it out of oil "Several times" that motor is boned on the first hit.    Does this guy think piling higher makes it stink less?

      That's interesting, I assume that would add to the cost of the oil but also I was forgetting to bring up the issue of the low tension rings allowing more oil past which in turn forces the cats to have more oil additives pass through them that wouldn't otherwise so they are creating that problem and of course its all in the name of fuel economy. Mind you the other issue would be the lack of additives that fight the formation of carbon within the piston ring grooves which turn the engine into an oil burner and with in this GM forums case is your average off the shelf Dexos licensed oil, meanwhile the other off the shelf oil being Valvoline's R&P isn't licensed and the only one that is which is that certain Mobil oil that came out recently ( its not even being marketed in Canada ) and only a fraction of vehicle owners are going to be using it out of all the other oils on the shelf or the quickie lube bay that meet the Dexos spec by way of actual licensing.    Also I suspect that its an easy excuse to pool the non turbo DI engines in with the turbo DI engines and design the oil to not have LSPI issues in the most demanding engines and short change the naturally aspirated DI by not offering a higher concentration of additive package they could handle and still not be at risk of LSPI.    I wonder if Amsoil flipped the switch just lately and did whatever packaging designation at the same time as I wonder what oil formulation I would have bought in May, of course I don't know when it was packaged at the factory vs how long it was in storage at the Edmonton warehouse. I know its been said at least in the past that the big players switch over to a reformulated oil but the packaging has not changed until they make that move as well so there is that cross over time where its a new formulation in a predated formula marked package.

      Hmm. A real reason to not just use the odometer to determine OCI?

      Sad thing is that this doesn't have to be the case. LSPI can be solved without a reduction in TBN. Swap Ca for Mg.  Cats are not a issue if the OEM can get a ring and valve guide seal even at SN levels of SAPS. Dizzy is purring like a kitten with a bowl of warm milk. 200K of Full SAPS oil and zero detonation issues and nice a clean inside and out. This shouldn't be an issue. It isn't 1920.    Tell ya what AMSOIL SS is excellent at, internal cleanliness. The new formula is even a step up from their already outstanding cleanliness levels. Can't say the OEM offering is quite that clean. There marketing suggest the SS is cleaner.     That is the only defense with at shelf oil. Nothing wrong with them if you ignore the marketing and OEM 'recommended' OCI and use a thimble full of common sense. 😉 You go sir.

      Roll up bed cover experiences

      By StingerZ16 · Posted

      I started with a folding cover by BAK PAC on my 2500. It went bad after close to 5 years. Bent and vinyl coming loose. Contacted BAK and they gave me a very good discount on a Revolver. Had it a number of years. Mostly outdoor storage. Some garage storage. Vinyl started to come loose. Still under warranty so they replaced to cover. Sold the 2500, bought the 1500 and got another revolver for it. Had it a couple years now and no issues. I store it indoors. Got a bit of discount when buying it as well. If you are seeing problems, contact BAK or real truck and let them know. Customer service was pretty good. But I think they changed their warranty.
