Hey Ted... Yes.. this was scientific and all.. lol And whatever you do the first piece of advice I can give you is to NEVER remove the battery cable.. It takes forever to re-learn itself and ends up only getting 200 miles to a tank until three months later it finally learns. I'm up to 325 miles a tank now and loving it.. If I reset the damn thing now it will set me clear back and give me no better performance. Ford has a way with programming these modules to have "Fuzzy logic" to control things in it's own way.. let's just say the computers have a personality of their own..lol and causing the computer to go "brain dead" as little as possible helps out the most. The G-Tech performance meter said it all to me... I could feel that it was stuttering and struggling under 4 grand.. But then it showed in my acceleration times.. Once out it came back up to better than original times.. (Last time I checked it was when the exhaust was first installed).. would you believe without the cap it runs .8 faster 0-60 and I also gained .2 by adding the resistor to the intake?? Hehe... It's getting quicker.. And I'm still on my 2.5 ... not on my 3.0 yet.

All in all after driving for a week without it (Which should give the computer time to adjust) It still runs the same as when I first un-installed the cap... It pulls harder in the midrange and it seems to pull just a little stronger on the top end (just a little)...

Adding the Mustang TB is something I'm going to do shortly.. As I have one sitting on my desk..lol But I still don't think that it will compensate for the TH cap.

Dom cool
