Ok how much differ is the ecu on a 99 3.0 and a 98 3.0,

Both are auto, ext cab. same damn truck just differ yrs.

But i have a chance to get a chip for a 99 will it hurt to put it in my 98 same truck? Differ part numbers from JET!

 

chips are programed per each specific vehicle so i dont think its going to work

 

i have a Jet and it only fits my 02

 

just save your money and buy a bama tuner........

Theres a guy at RPS that goes by the name BOSS 3.0, he is probably up there with bama. He knows the 3.0L vulcan like the back of his hand.
