Fellas, I have a LS swap oldie time car that currently uses the E38 from the 09' Silverado it came out of. No BCM etc, just engine and tranny (6L80E). I'm boosting more than 2 bar and I'm trying to find out of there is a E38 ECU out there that will allow me to upgrade to a custom 2.5 or 3 bar OS? So far I found the 2010 Camaro (I'be been doing the repository download roulette) had a 2 bar option but I have not been able to find a 2.5 or 3.
Edit: To clarify. I'm looking to buy a new E38 and replace my current one.
Thanks!
