I just had the lt4 hot cam installed. I have a granatenilli maf sensor. My car has been missing at high rpms. I would really not say missing but the performance just stops. spark plugs are new. I was thinking could the maf cause this problem. Should I buy a stock maf and see what happens??

 

I had that MAF on my old hotcam setup and it never gave me a problem.

 

did you have the emc retuned to work with the new cam? using the correct springs?

 

the gms SUX!! put in a stocker!!
