Performance chip for older ECU??

Earl Carothers · Oct 13, 2019

I have a '94 1500 with the 5.9L, bored over .03, kegged the manifold, shorty headers, cold air intake, aftermarket ecu, free flow exhaust, .480 lift cam. These have the older style ecu's and i was wondering if they have JET chips or anything similar for these older styles?? I

Question. Which aftermarket ECU is currently on the truck? Is it the Mopar Performance PCM?

If you don't already have the Mopar Performance PCM I would highly recommend it for a 94 model. It is an awesome piece of hardware. If I'm not mistaken I believe the part number for the PCM is P5249516.

I know my father had it replaced when he had it, ill have the look at it and see what it says on that part. If that's the case are there chips or tuners available for these older ecu's? Or

There are not many options available for tuning. The Mopar Performance PCM is the best choice for the 94MY.

If it were me, I would switch to a standalone EFI system so that I wouldn't be constrained by the OBD-1 PCM. With a standalone system you would have full control over the tuning.
