then youre pretty much limited on how much further you can go. id say with the right driver you'd be consistent low 13s, maybe high 12s with a good amount of traction. power wise is always different, but i would only assume you'd maybe hit 275whp on a perfect day.

for tuning you want to shoot for as high of timing as you can run cruising and part throttle you should still be at around 20-25* of timing depending upon where it starts knocking. this will help with gas mileage and the ability to feel the car running well at part throttle. for WOT i normally recommend 18* and whatever pulley you can run with it, but i am weird and like to run stock timing (16*) and more boost. your shift points are probably fine where they are now, if not a little high.
1. I didn't want to do cam with all the expense associated with it and overall drivability.
2. Pretty much same as part one. I had a friend go full size so I went with his ss since I hadn't really thought about going with an IC anyway.

How high is too high though? I have been upping my cruising Timing to upwards of 38* at 2200rpm (80mph) when at 5-10% throttle and as much as KR lets me with more throttle.

Running about 15-16* wot timing right now with the small pulley (2.85).

Thank you for making my day on the potential ability to run low 13s. pre-rockers I got my butt handed to me by a lightly modded ~2004 305-hp, 4.6-liter V-8 Mustang (modded after the stock 305, I think intake and maybe cat back only). So that made me think I might not be anywhere near 320 crank hp.

no wideband?
I might need to know more here... I have seen a wideband, but never used it to tune. I'm guessing this is only for WOT tuning as we can't change the A/F before PE?

ps. Thanks for super fast replies!
