I'm beating my brains out here. I stuffed a comp cams xfi 268 in my truck last weekend and now i am trying to get it tuned. B&G flashed my pcm but he aint got it right and i am thinking he not going to get it right. Anyone know of a hemi dyno tune or somebody that can actually tune these pcms?

Call KRC Performance. check www.krcperformance.com
I have the krc220 cam (bigger than the comp268) in my 04 Ram Hemi and they have the flash fix for it. Tell Marty that Jay sent you.

RUH ROH!! The damn hemis are getting tuned! hehe

KRC is definitely the place to call.
But, doesn't Marty send out the PCM's to B&G for the tuning? I thought that was the arrangement....
Eabigrick, what model/year truck do you have? Big changes from the 03 to the 04+ and sometimes the 03 computers take a few extra times to tune.

thanks colt, but the only thing i am worried about is mine is a 03 and i have the 16 bit computer system apposed to the newer 32 bit system. the other thing i am concerned about is i heard that b&g was doing their pcm work.

B&G is doing their flash but I believe it is a proprietary program. (It belongs to KRC).
The 03's are having issues holding the rev limit and speed limit part of the flash but from what I have heard the cam part of the flash is taking. The 04+ are taking all parts of the flash fine.

eabigrick

that is exactly what happen with mine. he told me that it wouldnt hold the rev or speed limit but he could flash it for the cam. it is running better but it is still running rich and causing a check engine light. i am just not satisfied with what he done. is it possible to change to a 04 pcm? that 5800 cap is killing me need more rpm.

GS motorsports has a deal with paxton on their supercharger kit that has a piggy-back deal for the 03's like mine. Perhaps they will offer something for the non-supercharged set-up's, it's worth a shot.

I thought KRC tried or did swap out an 03' PCM with an 04' but can't remember. It might have been 04-05 also.
The other computer change in the 03-04 was the integration of the TCM - tranny module to the 04'. It was separate in 03' and the reason why us 03' folks were able to alter the torque management wire. It could be an entirely different wiring harness.
