Howzit all

I'm wondering which chip is best for 5.4 4X2 Screw. I'm considering one from Jet Performance or the Superchip. Any recommendations of these or others. Or maybe even some proven data. I'm also laoboring over Gibson & Flowmaster catbacks. Installed already is a K&N Gen II and soon a Throttle spacer. Any helpis appreciated

Hey go with the Flowmasters! I just put them on my '02 Supcrew and love the boost and the sound! Let me know about that FIPK. Im gonna do it this week but would like to hear some feedback first.!

 

Gibson; Airforce One; SuperChip..!

and Love the power.!!!!

 

Do not get the Jet chip. It only works at wide open throttle. I am going with the Diablo chip. The Diablo chip works at any throttle position. Check out the threads in under computer chips before making our decision.

I have Flowmaster 50 series on mine and love it. It has a tone similar to a stock mustang. Sometimes I wish that I would have gotten the 40 series, but over time it will get somewhat louder. As far as the TBS; I've heard that they are not worth it. I have the Diablo chip and notice alot of performance there at all RPM's, but you have to run premium. Any way you go should be better than stock. Good luck!

 

I got a noticable increase in power from a bassani cat back system. Airforce-1 installed after that but didnt do much. I will be adding a chip and ATI procharger in july.

 

was is the ATI procharger?

 

Gibson Super Truck system works great for me, easy install also and easy on the $$$$. rk PS sounds awesom also
