Got a dyno tune

[Whaler]

I was having problems with my truck leaning out, so I took it to AVT Performance in Conway, SC. Lightning Mike was nice enough to go with me to pick it up and it seems to run well now. Power is down just slighty, but the A/F is better than it has ever been. Truck made 440hp/524tq on the street tune with an A/F of 11.8 across the RPM band and 413/513 on my towing/cold weather tune with A/F at 11.8 and dropping after 4,300RPM. I do have a tune for C16, but I'm going to have to figure out how to pump the tank dry for that tune. The transmission is also shifting well, now. The mass air sensor was bad. I'm glad I wasn't running it hard while I was having problems, or it could've gone KABOOM. I guess I might keep the truck, now. The Trailblazer SS will have to wait.

I'll let you know when I'm going, since that doesn't happen often. I have been known to make a pass every now and then.... :lol: Maybe a seven this time.

what mods do you have?


4lb lower pulley, ported Eaton, E-fan, SCT 2400 mass air, 60lb injectors, C&L Plenum and elbow, Accufab single blade throttle body, upgraded heat exchanger, Magnaflow catback, rear cats removed. I think that covers it.
