12cm is only really good for std. tranny, otherwise you should us a 14cm or a 16cm, your etg's will go up with a 12cm

you should update your signature so we know what you have

12cm will really get rid of the lag but when your on the pettle it will make the etgs go hi, i would us the 14cm you get rid of the lag and you will get alot more preformace, and lower etgs

Your egt's will go higher with the 12cm depending on how you drive, the type of terrain and THE AMOUNT THAT YOU POST IN CAPS@!!!!!

my crew had a gated 12 on it. its a real nice housing with a 5 speed. i had a couple turns on the fuel screw and pod's. with a loaded 24' enclosed trailer i could hit 1500 if i ran it hard, but i had to try it in order for it to do so. with stock injectors and a not too much turned up pump i think you'd be fine.

try it, you'll like it. i promise.
