wanablaze Posted January 4, 2009 Report Posted January 4, 2009 Yesterday I took my truck to get tuned. It is completely stock and it laid down 272rwhp. After getting it tuned, the truck responds like it should have from the factory; instantaneous throttle response and a bit more power. I also had the shift points raised from 5500rpm to 6k (the rev limiter was 6100rpm from the factory, so that got bumped a few hundred rpm higher also.) The transmission torque management was not touched. When I saw the first graph, I was very happy with the results, especially the torque curve. Then the tuner dumped a little more fuel at peak torque, and the second graph is what we ended with. The truck feels much better and I love the VVT, makes for an awesome power curve! Quote

black00chev Posted January 22, 2009 Report Posted January 22, 2009 Thats very impressive... Dyno tunning is the best hands down. How's fuel economy for you now? Quote
Tkenmore Posted February 1, 2009 Report Posted February 1, 2009 Do you run 87 octane? i have had my truck tuned as well. But my tuner didn't go to wild since i thought i was going to be towing with it more, and i cannot run more than regular 87 octane fuel. Quote

But my tuner didn't go to wild since i thought i was going to be towing with it more, and i cannot run more than regular 87 octane fuel. when I bought mind I was told from the factory thy have a 02 sensor that ya had to run 91 octane or better I dont know from day one I have put nothing but the highest Quote
F1SSS Posted February 2, 2009 Report Posted February 2, 2009 Im even afraid to put Cumberland Farms 93 in my tank. The SS and Vmax have the same engine, I am guessing you should be running 91 minimal. Quote
