I resently bought a 2010 F150 STX 4.6L. Ive always liked and perfered 80 model trucks because i could work on them and do anything performance wise cause i know how. Need help with the performance side of my new truck. Ive installed a 40 series single in dual out flowmaster, super chips flash paq, and have cold air intake and throttle body spacer on order. Wasnt pleased with the superchip but it helped. What more can i do with out major engine and transmision work. If anyone knows of anything i havent done please let me know. Thanks

 

Return the TB spacer, you just reduced performance and wasted 90$. That's the first performance mod you can do. Besides for what you have done the only other things you can really do is Supercharger/turbo, or NOS. You can re-gear as well, that's about it.

Also your probable suffering from a lean condition making your performance gains non noticeable. Did you get a custom tune for your intake and exhaust setup?

 

The superchip flashpaq wont let me do that, like i said it help a little bit but im was sure it would do more than what it did. Im very limited with my tune settings. Raised rev limiter, raised speed limiter, octane preference, tire size is about it and thats in advanced tuning. I think i made a bad decision on the superchip

 

what about some headers?
