hey,

ok, i have a '06 'stang GT, i am in the works of putting ona pypes exhaust, part #RPM-504601-F, and the PULLEY/C.O.P. kit, Part #RPM-504601-A, from http://www.rpmoutlet.comand a JLT CAI model #CAI-FMG-0507 from http://www.jlttruecoldair.com/ok, i know for the cai, u need a dyno tune/re flash, and for the exhaust, u dont need a dyno tune. the question i have is this: do u need a dyno tune for the pulleys, or the C.O.P. kit? i plan on putting the exhaust on this weekend, and the pulley/cop kit also, if a tune is NOT required. i will be getting a dyno tune in march, and that is when i will be installing the CAI. i dont want my car going into "limp home mode". any help would be greatly appreciated!

You only need a tune for the CAI.

do it right from the start cai and a tuner, like a bama chip's tune. Imo.

RPM OUTLETS GOOD OR BAD?????

Stay away from them and get a combo from Bama, Brenspeed or VMP

*whew* dodged a bullet! thanks, i didnt know rpm was so bad.......however, i dont have anything bad to say about them. i received all my parts 4 days after ordering, and they are all the correct parts. man, im glad i didnt get screwed. i didnt know about http://www.resellerratings.com, but now i do! hey, does anyone know how to identify what axle ratio my car has? its a '06 GT auto, if that helps at all. thanks!

Nuke

The axle ratio code is on your info plate inside the drivers door frame AND there should be a tag on the rear axle's differential cover (if it hasn't disintegrated). There are a few threads that you should be able to find with a search to tell you what the code is.

3.31:1

In '06 it was 3.31 for autos and 3.55:1 for manuals.

Beinning in '07 the 3.31:1 was standard everywhere, and 3.55:1 was an option.
