Hey guy's, Does anyone know where to get a custom tune done for the inune? Im in northern Illinois and put the 91 tune, firm shift's, 20% throttle boost. All I've done to my challenger is the CAI, and a stock exhaust off a 6.1. So far so good, but always looking for more power. A little shocked that it doesnt spin them that easy from a dead stop, and yes i have traction control off, 25 mph and holding the key to the start postion....

You will prob be better off asking here http://www.challengertalk.com/forums/f63/

no help with the tunes sorry...even with those mods I doubt a 3.5L is gonna break loose the tires...new gears might do the trick...dunno.

You can always call Tim at Mr Norms in Rockford

Stock my 3.5 would chirp the tires and with the 93 tune you could hear and see the tire spin several times when you floor it. Last spring I installed the throttle boost in the Predator and on the 1st 0-60 run without power braking the tires started spinning and for the first time the rear twisted sideways to the left, like a HEMI, like she was sitting on ice! After installing the throttle boost program the tires always break loose and spin without power breaking causing me to waste time and run slower. You can use Amsoil octane boost to bring your 91 up to 93 octane and run the 93 tune. There are threads about putting too big of an exhaust on a V6 and losing low end power which you may have done by putting a SRT8 exhaust on your 3.5. Here is a stock 3.5 breaking the tires loose.
