Anyone know of any kind of results other than 1/4 times to show comparisons for any kind of tuner, nelsons, wheatleys, PCM4less, westers? There needs to be something to show who has more expertise in different fields of tuning. I guess location really is the biggest factor in determining a tuner, because I guess I have yet to see any one person be picked over another solely because they are better at tuning.

I do know that PCM4Less tuned one of wheatleys customers that had a turbo on a 5.3L. They put it on the dyno before and after wheatley tuned it. when it had wheatleys tune it had 30-40 more hp than when it had pcm4less's tune. I cant remember where I read this at. It didnt give any comparison over stock tuning. But it does seem weird, bc Ive heard wheatley doesnt have much experience with F/I.
