So I plan on installing some FI HFC's but I keep reading mixed reviews.Some say a tune is not required and some say it is. I already have the intake and exhaust on the car and the only problem is the closet place to get a dyno tune is a couple hrs away ...... Has anyone with a intake, hfc and exhaust ran without a tune with no problems? How many miles has it been?

 

A tune really is required to get the most out of the mods, and make sure you're running a proper A/F ratio... plus its a toss up whether the HFC will throw a CEL or not without the tune. Good news is you don't need a dyno tune tho. I'll send you a PM
