just put whipple 2.4and ford racing 90mm maf seems to idle ok then starts runnig rough and comes out of it when i touch gas then in a little bit does it again . Anybody have any idea?

 

Have you tuned for the 90mm maf?

 

^^^ x2


and is the MAF clean??

 

Stock 8PSI whipple comes with like a 80mm ish MAF Housing. If you are runing a 90MM you need a new tune or it wont work. The MAF tells the computer how much air flow is going in the motor by reading a small portion of air and based on the size of the MAF it can then compute the amount of total air coming in. If the computer sees so much air through a 90MM MAF and its computing for a 80MM maf then it will run like poop if it all.

 

Thanks guys I had computer tuned but I don't remember if I told him it had a 90 mm . I put this L set up in a '63 galaxie Ive had some fast stuff but I think this tops them all, it flys THANKS
