Help with using HP Tuners
So I just bought the HP Tuners new MPVI3 Tuner and have been making some basic adjustments to the Timing and fueling tables as well as turning both fans on sooner. I've also increased the transmission line pressure from 90 psi to 95 psi and increased rpm shifts a little as well as a few other minor adjustments. I just don't want to mess with too much because I simply don't have very much tuning experience. I need some help adjusting anything else I can to get the most performance gain and to improve overall drivability. I know that you can get a good 30+ hp out of these stock LS1's as they to come pretty de-tuned from the factory.
Id really appreciate it anyone with a good amount of tuning experience could help me out!
Thanks in advance, Scott!

I'd start with the C5 tuning area https://www.corvetteforum.com/forums...n-and-tune-91/ and https://ls1tech.com/forums
I've not tuned w/HPT. But years ago I used to tune fords w/SCT. One thing I'd do on a stock car w/auto trans was refine the mass air flow transfer function. I found that transmission functions became more accurate as to what was commanded. Idle and low speed smoothed up too.
