Ok, I added a ls1 hotcam kit to my GTO along with a underdrive ballancer. I also have LT's, and no cats with spintech mufflers. I just got a tune this weekend, and she put down 368/374. It seems fine, and I think I am going to keep my Predator for small things. My question is this, On the 70 mile trip home, i was watching my LTFT's, and they were staying about a +7 at 2300 RPM. When we tuned it it was mainlly on the Dyno WOT, we only cruised around for about 15 mins messing with the shifting. OK if I mess with my cruise LTFT's now, will it affect any of his tuning? Thanks guys!

part throttle fueling DOES effect the wot fueling. If you adjust them, you should go back to the dyno to readjust your WOT

yeah, they should'a tune it right - need to do part-throttle tuning first, then WOT tuning...
what you CAN do tho is... go -7% on your injector slope to get your part-throttle fueling dialed in...
then go into the PE fueling section, and also go -7% in all rpm ranges...
this will essentially remove the extra fuel at WOT that is added by goin -7 on your slope adjustment, so that your PE/WOT fueling should stay at about the same level as what they adjusted it to be for your WOT AFR...
