I have an '07 new body style Silverado with a 75 wet shot. It's untuned, but I look forward to being able to tune it soon with the new update. Obviously, I cannot advance the timing any more because of the spray. If anything it should be retarded 1-2 degrees, but it runs fine on stock timing and premium fuel with the small wet shot. I was thinking about advancing the timing below 2500 rpm which is where I shoot manually, and leaving it stock from then up to redline. But since it's on motor most of the time, it will basically have stock horsepower above 2500 rpm. I also thought about making a separate agressive timing tune for strictly off bottle. Is this the only way?
