have you change the external Tranny and Fuel filter lately,try that and i think your problems will go away and to keep that from happening again keep them change every 8k to 10k miles..that is embaressing if a hemi beats you,in your other thread i mentioned doing the PPE and with that on there you'll have to give him a head start so you don't beat him to bad..

When is the last time you changed your fuel filter? That will cause your tranny to shift weird.

thanks for the advice what other upgrades would i have to do besides the ppe to support my new found power? i know i would have to do transmion stuff but what about the fuel system, manifolds, intercooler, water methanol, internal work i just find it hard to belive that i could get that kind of a power increase with just a chip and not have it destroy my engine i want 500-600hp if i can do it for around 4k including transmision stuff is that possible? thanks for all the help guys im new to diesels its all good so far
