Having just fought a lot of issues doing just this here is my recommendation for least amount of headaches. use the 6.2L tune with 6.2L MAP, MAF, TB, Pedal, and injectors. Changing any of these...

I have been reading DCFO, popping, and burble threads for hours and need some input to get rid of decel popping that has at this point destroyed my wideband trying to figure it out.

2009 5.3L...

I think the main reason that info is hard to find is that this part number was only used in the 05 to 07 Corvette and GTO. Not a lot of vehicles out there using this injector

If you google search "GM 12569113" it comes up everywhere.

They were in the box of parts the previous owner had for the engine, not in original packaging but looked unused. Looked like ebay purchase. They look identical to the bosch GM injectors that were...

I was able to get this sorted out but I am still left with some questions.

I installed an adjustable pressure regulator in a returnless style configuration and set the pressure to exactly 58psi...

Thank you guys. I was hoping I could just run higher pressure without damaging anything haha. The flow rating of my current pump is 50gph at 75psi. Quite a bit of overkill for a ~400hp motor. I found...

I have been doing a lot of searching and cant find a solid answer.

I have a newly built "LS2" 2008 5.3L truck block with DOD delete, 243 heads with new BTR lifters/pushrods, a mild crane cam...

Thank you. The ECM wasnt going to work with its current OS anyways so I ordered a New programmed ECM for an 08 Corvette with everything configured by them for the hardware and sensors I am running....

Scratching my head here. I have a fresh standalone tune on an 08 silverado E38 in a car with manual trans (I know the vss will be inop, fixing that) and after about a minute of idling it revs to 2 or...

Got it. I had pretty much determined that from you telling a ton of other people the same thing in the forum over and over again haha. I don't have anybody local with the GM tools willing to work...

Thank you for the info! No, this is a swap. Don't care about the VIN at all. Just don't want to tell my customer we need a different ECM when we are being told the impossible was done with this one...

Understood and thank you for the quick reply. To confirm, a auto trans truck VIN could not possibly have an manual trans OS flashed without also changing the VIN?

This is what I'm being told was...

This is my first Gen IV after lots of gen III builds over the years, many for customers. I'm having some issues that seem to be common but after hours of searching every term i could find or think of...
