Have you checked all the vacuum lines? they can cause bad surging. Also have you tried cleaning your MAF and IAC?

[SN95/Victory]

yes to all your questions. I've even pluged them off at the manifold to check hoses. I've been told now that this is a problem with 94-95 PCM's they hate cam changes. So it's spend another grand to fix or pick stock cam back in. Will probably do the later. Thanks for your input

Have you had a chip burned for your car? My dad (GTS 5.7) has a 95 GT with cobra intake, f303 cam, AFR 165s, 30lb injectors, 73 mm pro-m MAF, 70mm TB, and all the bolt-ons. Got a chip burned and doesnt have problems.

Any major upgrade such as cams will need a cumputer tunning also!!

Your cam does not have enough lobe separation. You need one of these:

Product Details
Steeda proudly offers the #19 Cam, similar to the popular #18 Cam, but with a slightly wider lobe separation angle for better vacuum at idle which is required by the more sensitive 94-95 Mustang processor. This cam features a split pattern which favors the exhaust side, and a wide 115° lobe separation for low overlap, making it an excellent choice for supercharged engines.

Recommended RPM Range 2300 to 6000
