I figure the predator base tune is worth about 10 hp...

Another thing i hate about the custom tunes is they do as much "guess and check" stuff as you would on your own, they just have the flexibility to adjust at increments... but without being physically there to look at the dyno info it's a pretty inefficient system... However, they're normally pretty close... I had a custom tune for when i put my LS6 Intake, TB, and Pulley on... first run i was 12.5... pretty fat... the tune leaned me out to 12.8-12.9 which was a good thing but i didn't pick up any horses... I also had alot of knock coming from an older to piece ASP (I'm positive it was that since I swapped to the SFI approved and pulled my buddy who was dead even with me on the older one). If you have enough runs to play with it, see where you A/F is running, then add a couple of degrees timing, monitor the knock sensor, make sure you're not pinging... if you have a good 13 A/F then put as much timing in as you can without pinging! that'll be the best power your car can make!
