Diablosport Forums

Hi, I have a U7140 and a 2006 Mustang GT with FRPP Hot Rod cams. I have an off-road x-pipe, and the car smells extremely fat at idle, whether hot or cold operating temperature (smelled fat when CATs were still in place, too). I recently had the car dyno-tuned, but the only tweak made according to the tuner was A/F between 4 - 7k. He did not touch 2 - 4k.... as he said it "was right where it should be." My tunes came from Doug at Bama Chips after I installed the cams, and the car would die during cold starts, so Doug tweaked the tunes for me. However, now I have this extremely rich condition at idle, and we all know what happened with Doug. Is there something in the A/F I can tweak to accomplish a happy medium? It is to the point that when I start the car and let it idle for more than a couple minutes, it makes me sick. I cannot even drive the car any more. I have the latest revision, too.

Thanks,

Jim

Time for some custom tuning, only way to get cams dialed in 100%.

Well, I would love to do that, but it took me nearly a full year to get on a dyno that tuned DiabloSport here in St. Louis. Then they charged me $300.00 for 4 pulls, and all he did was lean out the top-end. I have just about every bolt-on mod you can think of, and it only made 310 RWHP and 307 lbs. Any ideas?

Thanks,

Jim

Were they a CMR dealer?

Custom tuning is a MUST with any cams....

This is up to date to the best of my knowledge, but I have a nagging feeling I have forgotten something.
