dyno tune?

Everyone i call says alls they can do for me is timing and adjust the fuel pressure..i thought there was more to it then that? Correct me if im wrong, i dont know much about dyno tuning

is it because my car uses speed density and a prom?


I sched with a company to do 2 pulls and get the wideband o2 data and i guess ill figure out what im going to do from there... (its only 65$ to do this..while tuning and 3 pulls or more is 150$ an hour)

any suggestions?

They likely dont have the hardware and software to make changes to the prom.

How far are you away from Jacksonville, Florida. There is a guy there that will do more than that.

Vinci perf. in Orlando also does OBDI ecu dyno tuning, but at the money, either DIY prom or switch to an aftermarket ecu...then if you change something else down the road, you're not dropping another $500+

We dyno tune ourselves at the dyno for $75 an hour with up to 10 pulls as a group.
