Well, went to the drags today. The sucker ran a 15.7. So, in trying to find the problem, I pulled the plugs. The porcelan is as white at a white t-shirt, and the metal part of the plugs looked like it had been dusted with flour it was so white. I had a custom chip made without a dyno tune and the tuner said that my 24#ers put out enough fuel that he'd have to lean it up a bit to get it to run well. Thus, I took out the chip, and gained about 3 tenths. It was so lean it gained power, and pulled a bit harder when richened up, not simply running cooler. The hotter it got outside, the better the puppy ran, until an incredible blazing 15.166 with a trap of 95 mph. Not Cool out of a mid 13 second car (see mods). Anyways, I've put on about 1,000 miles with the chip, with the car running quite dangerously lean. A couple experienced racers commented on never. ever. seeing a plug that white. Pure white. Anyways, I'm in northeast colorado, and am looking for a dynotuning shop within 500 miles, perhaps more. I don't care, but I'm not burning up a piston. Does anyone know one in Colorado, Wyoming, Nebraska, Kansas, anywhere, if you know anyone within my 1/3 of the US, please do tell.

thanks,
Lance

Get rid of the C&L MAF! Put your stock one back on...problem solved. Seriously, do this and hit the track again. Those C&L MAF kits are designed to lean by 30% and you can't fix it w/o a dyno tune. I had the same problem with my car.

Your chip maybe further adding to the problem by advancing the timing with the already lean condition.

Sorry I can't be of more help, but I was just visiting Denver and saw a Mustang shop near Golden, CO.

Yes the MAF could be causing a problem but not that lean. That is a fuel problem.

Also, you forgot to get gears .

Gears should be one of your first upgrade IMO. It wasn't my first time around and I regreat it so this time gears and exhaust are first on my list.
