oh yeah, PM me if you'd be interested in purchasing a used pro-M 80mm MAM calibrated for 24lb injectors, for cheap

The cobra intake and mam and 65mm TB will support way more HP than what you are making. Roughly about 425 FWHP.

The heads are the bottleneck.

I know people with the GT-40 intake on 351 based engines making over 400RWHP through a 65mm TB.

There are a number of things it could be. Maybe the cam is a tooth off??? I doubt it but you never know. I am not sure about the 94-95 cobras but the 93 cobras have a mass air sensor calibrated for 19# injectors even though it has 24#er's the ecu makes up the difference. So be careful buying a MAM calibrated for 24# injectors.

I dont have a scanner so I cant post the sheet they gave me. I appreciate the offer on the Pro-M unfortunately one is already on the way ordered two days ago. I put one the new 65mm TB and will put on the 76mm MAF nad CAI when it arrives and get it retuned. It idles now but will die if you turn on the AC, also the exhaust smells real strong.

The cam was installed straight up dont think that's the problem. The stock TB was 60mm and was replaced today with a 65mm. I will reuse the stock electronics on the new MAM. 94-95's are like the 93's the MAM is for 19's and the j4j1 modifies it for the 24's.

I figured the heads would be a bottleneck but did not figure they would hurt me that much. I cant afford new ones right now but will get some next year when the motor is still low mileage.

Thanks for the input guys it has been a great help. I'll post the new numbers after getting her back to the Dyno and the chip retuned.
