1) what is the truth about performance chips, do they really save fuel economy while adding hp???

2) how much should a p chip cost???(only asking because iv seen them around $25)

3) how much does a cai hurt fuel economy??

 

I have never heard of a "chip", but a tuner adds HP and better MPG. And a cai dosent hurt MPG, if anything it improves it.

 

Get an sct tuner from bama! Can't go wrong. Simple easy and tunes for life!

 

Those 25 dollar Chips are nothing more than resistor that richness the fuel mix. Get an Sct from bama. Done deal

 

what exactly does a tuner do (sorry for the general questions, iv just started getting more into hypo cars and out of trucks lol, so thanks for all the help)

 

Go look at americanmuscle.com ....

 

the tuner helps you adjust the computer in your car when you add say a intake. You would also use a tuner to adjust the computer when you change rear gears or tire sizes so your speedo will read correctly. I throw another tuner you can call for advice and parts. Give Breenspeed a call. Where are you located Frenchy?

 

Indiana

 

Thats where brenspeed is located.

 

Yep. Plan a trip to brenspeed and talk to them. They do dyno tunes, and everything mustang..

 

Like said, got a tuner instead.

And a CAI is a waste of money, a K&N drop-in filter with the silencer removed does the same thing, and looks better too IMO.

I had an ebay CAI on my car a few years ago, and after a harsh scandinavian winter it started to pop "A/F mix too lean" codes, I ended up trading it for a K&N drop-in filter, and I have been happy ever since.
