rocket chip doesn't list prices that I could find. how much was the tune?

Check out www.greendieselengineering.com

$700

But that includes the tune and the ODB unit.

I've already spoken extensively with GDE and they offered $100 off if I posted on social media with my experiences about the tune. thanks for the post otherwise.

Stage 1 is $385.

How is the rocketchip installed? Do you have more details about it? thx

I believe on an 05/06 it would be done from the diagnostic port....but on my 98 two chips on the ECU had to be replaced. The Rocketchip web site has a FAQ that answers a lot of common questions.
