MustangMaster, Glad to see you got rid of the GMS CAI and went with FRPP CAI. My GMS CAI is setting in the garage collecting dust. Live and learn. Hope to sell it to someone who does not want to tune. As with you, t worked great until I decided to start running a tune and problems.

Yes, just everyone esle said....aftermarket COP's are the worst. On the other hand, that wouldn't stop me from modding my car tho. You really should only mod your car if you have the money to. JMO!!!!

too bad the Granatelli CAI didnot work for you...I still have mine tuned by Brenspeed and no issues.

SteveB_Ret, thanks for the recommendation again on the FRPP from the GMS. I posted on an earlier post that I don't really see a power difference but, do see a overall smoothness of operation difference. Warms up smoother/quicker back to normal idle better too.

TPony, after everything I've tried on trying to get rid of my car skipping/missing, I think I would have been fine leaving the Granatelli CAI on and just changing the Granatelli coil on plugs back to stock. But, I feel even safer having the FRPP CAI with new Brenspeed tunes for the car. One great note for Brenspeed, and when I ordered the FRPP CAI I told them this....when the car was skipping/missing, the car ran best with the 91 Brenspeed tune. If I returned to stock and put the GMS wiring harness back on the GMS CAI the sputtering/missing was way worse. To me, that means they have great tunes.
