Jeep Strokers

I am new to the stroker motors. I am trying to find out how far I can go before it starts causing problems with the PCM.

The PCM won't mind the extra displacement, a ported head, and external performance bolt-ons 'cause it can read the MAP, TPS, and O2 sensor outputs and make the necessary adjustments as long as the injectors are appropriately sized. Things start to get a bit dicey when you deviate far from the stock cam specs but as long as the cam is mild enough to generate good intake manifold vacuum at idle, you shouldn't have any problem. Chris@christuned is "the man" for OBD II PCM reprogramming so shoot him an e-mail.
