You're probably too rich... just get it dynotuned.

Whether you drive the car or not you still need to dyno it with the 60s in it. If the car won't run with the 60s you could drive it there (under 3000 rpms) and change them in the parking lot, get the tuner to change them or change them at your house and trailer it there.

RE: Installed P1SC need help

Ok...I changed the gap on the plugs and retried the 60#'s it still ran tooo rich so I swapped them back to the 30#'s and I also found out there is a stock mass air with the kit so I got a 90mm mass air....so I am going to change that and somebody told me it should run alot better and hopefully I can get it tuned this weekend.....

You don't nessicarrily need to trailer the car to the shop. If the car will run with the 3x pound injectors and its not running super funny etc.. just drive it REAL easy to the dyno shop and you can get it tuned.

So long as you stay out of boost and don't floor the car you should be able to drive it normally to the shop, unless the tune is so far off its simply running like ****. When your out of the throttle and staying under about 3000 RPM the car is bascially a N/A setup.

Whatever you do, do NOT floor the car again or take it into boost until you get the tune checked out. Drivinghard/into booston a stock bottom end with a junk tune is a nearly guarenteed blown motor on a stock shortblock 2v 4.6

04.. your running a 12.1:1 a/f? Thats a little lean isn't it? I have mine down around 11.5 just to keep it safe, but I wouldnt go past a 11.9 on a stock shortblock car, intercooler or not.

My tuner said 12:1 is still very safe on a stock shortblock. He told me 12.5:1 is pushing your luck tho. I have had it at the track and gotten on it several times passing slow pokes on two lane roads. It runs smooth and strong with no signs of detonation. 12:1 a/f with 19* of timing is what I'm running with no problems.
