Im looking into buying a tuner. What kind of gains can i expect, i've got CAI and dual cat-back exhaust already. Also, not sure which tuner i should buy.

 

which kind of CAI do you have?
is your car an Auto or Manual?
xcal2, or the predator are the most common that ive seen. personally i think im gonna go with the xcal2

 

I like my X-cal2, it is a very nice programmer.

 

If you're running an auto, the x-cal2 is the way to go. If you're manual, i'd say it's a toss up. Go with a tune shop like brenspeed or evolution performance, don't go with the tunes from the tuner itself.

 

i've got BBK CAI on it, and Flowmaster exhaust, and its an Auto

 

if you have an auto, the tuner is going to make a bigger difference


you will see some better shifting, and better throttle responce. also, you will gain ~12rwhp, which is pretty good. it does not really matter what kind of CAI you have, there is only maybe 4rwhp differnece between the 'best' and the 'worst' CAIs after the tune

 

X-cal2 from Bamachips is the way to go! Doug is a great tuner.You can expect considerable gains both in HP and vesatility in any other mod you do. It was my 2nd mod after the K&N CAI.
You won't be soory with the bamachips X-cal2

 

"BBK CAI "

how do you like the BBK, did you see some HP gains?

 

theres a great write up on this under 4.0 FAQ sticky entitled look here before asking about tuners...i learned a ton there
for a BBK though ide go w/ an xcal2

go w/ a diablosport if you have C&L they worked together and the diablosport specially helped to make the new cai for C&L that a lot of guys have on here...the combo of the two is supposed to be great....xcal2 is your best betgenerally speaking though

 

i just got the xcal 2 and the c&l cai from evolution performance yesterday...feels great, you dont even feel the shifts now. much faster performance... very easy to use as well
