so i did a bunch of stuff ie., c&l maf, 62mm twin throttle body(motoblue), and underdrive pulley kit(also moto blue). well we installed it and tune it with the pred performance tune and i got 0 throttle response when i stepped on the gas. so the following mon called diablosport and downloaded the c&l tune with 91 oct. loaded it and nothing on the throttle again. so i changed out the now throttle body with the stock and whoala. i got a response only i was running 89 oct. so i downloaded yet another tune and back to the car i went. now from the get go i had an failsafe engine mode running in the console and only after i loaded the 87 c&l tune had a check engine light on. so being sick of it brought it to the dealer, and reflashed the original backup. my guestion is once the ford people fix this and put it all back to their stock computer settings will i be able to drive it a while with the c&l maf still in it? what kind of issues do/will i have--thanks

The C&L allows a lot more air in. This has to be calibrated for or you will run too lean. I am not familliar with the Moto Blue throttle body. Do they offer a tune/upgrade that compensates for it?

According to the diablosport web site, anything other than exactly what they had a tune for, they require you sending the unit back or take it to a diablosport dealer and having a "custom" tune loaded. I am begining to think I should have stuck with a dybo tune and not bought the predator. It is seeming like a waste of money right now. Any question I send to their tech department is the same answer.....take it to a dealer and have a custom tune WTF

you can add a couple of more fuel points via the predator i think... it's definitely something you'll want to do gradually while data logging. if you want some real info on self-tuning, you might just talk to a dyno tuner and let him know your situation.

idont think moto blue has a tune for their throttle. ive done a lot of research and all the throttle bodies ive looked at , which has been limited due to the fact the stang is so new, but no their are no tunes for the throttle bodies. thanks for the help, Ive found out wtf was wrong with it. fyi make sure if u turn your car into the dealer you reinstall the original backup , but i guess i had a faulty sensor so it was covered under warranty. im gonna fix the rest / tune the car on friday and keep you all updated thanks again
