INFO:

I have actually tuned this Tahoe before, but it has came back with a larger set of 80 lb injectors and a new torque converter, so it requires some tuning updates. naturally, it doesn't go smoothly. virtually every time I make a full throttle test, a tube somewhere blows loose. But after finally getting some decent data, it appears the truck may have some larger issues that I will have to dig into to figure out exactly what those are.
