Hello from Utah!
Cut my teeth on a Gen 1 SBC that's in my 84 vette (avatar picture), currently running an EBL Flash, mild cam, aftermarket intake and heads...
Bought a new to me 09 Tahoe with some miles on her, then learned all about the DOD/AFM system.
Right now i'm preparing to tear into the old hoe to fully gut the DOD system.
I have HP Tuners, and know my way around it a bit.
Just have not done much in the way of tuning a newer system, so far i have done MAP tuning only.
Still deciding if i want to mild cam the old hoe, or just toss in a LS7 camshaft and be done.

Hoping to get some direction on exactly what is actually needed to get the engine running should i go a little more aggressive with the cam.
