I just recently added a 3" exhaust (replaced the rear cat with true 3") with flowmaster and the K&N FIPK to my '93 F150 5.0 w/E4od. What chip would I install for this application? What type of performance increase would I see and are they Calif. smog legal?

Thanks,

Wes

 

If you want CARB certified your choice is narrowed down to basically Superchips.

 

Ken,

Can the chips be removed for smog certification without a problem? If so what chip would you recommend? What type of performance increase would I see and how much can I expect to spend?

Thanks

 

Yes, they can be removed and it returns to stock but I can't advocate it (liability). The Diablo for the 5.0 gives roughly 20 HP, assuming the engine is in great condition. The older V8s have larger tolerances and HP can vary.
