anyone know the difference between a jet performance chip for a 98 3.9L ram and one that would be made for a 94?
the way i see it is, its the same engine, the same size truck, and the same model, i dont think they changed anything until after 2000
but then again i might be wrong and a chip made for a 98 could really eff up my 94
any input is all some

 

they make all kinds of stuff for your motor... 50 mm TB, cat back exhaust (I think you found this already) 1.7 Roller Rockers, double roller timing chain, crank pulley to name a few...

you want a richer AFR... do the IAT relocate mod, want high end HP, mod your intake, want to advance your ignition timing? do the crank sensor mod...

there is all kinds of stuff that you can do to your motor to make it perform. but your gonna get your hands dirty doing it...

 

yea im just havin a hard time findin it
everytime i read up on somethin i wanna do to juice the hp its always like "98 and up" or it doesnt list my motor at all
i dunno maybe im lookin in the wrong places
i did get the k&n intake that was no problem, but it said that it was specifically for what ive got
ill keep lookin

MSD Coil (found here pn 8228 I think... a MSD spark box will most likely not work on your motor but the coil is a drop in replacement)

Sam at SOCalDakota can most likely get you a cam ground for your motor... ask him he is very helpful!

hope this helps some...

 

On the topic of chip compatibility, there were changes made to the electrical and diagnostic system between 94 and 98. Dodge went from Pre-ODBII to ODBII. And if chips are anything like reprogrammed PCMs, then it's not going to work with your truck.
