I haven't bought a device yet, but I am trying to figure out if there is a tune in the repository for an E38 (2009 avalanche) with a high lift TSP truck cam and long tubes. Or something that would give me a functional starting point?
I realize that this is kinda like asking for free stuff...but I am in the middle of the engine work and decided to take the plunge instead of getting another mail order tune. But I have never worked with HP tuners before.
Maybe a better question...is there a guide (ECM specific??) somewhere that defines a list of variables or parameters that need to be changed when making certain upgrades?
