I'm going to be getting a base line dyno mid month here soon, then headers and hopefully a true dual al lthe way to the back.

after that I was going to go and dyno again, and was thinking a dyno tune would be great right... but how?
will the shop have evertying needed to tune it? or do I need something done?

Any help would be great, thanks.

oh, and what gear is closest to 1:1?
I have 3.42 gears and hte BW M6

 

Your cars own computer with be able to "learn" what is needed to get the most out of the motor with the type of mods you are going to do. So it would be good to get a baseline HP and Tq # and see what the headers and exhaust give you. But I would say a dyno tune at this point is not necessary. Good Luck.

 

Very few dyno shops would just happen to be able to tune your computer. You'd have to arrange that with the tuner, not with the dyno guy. But I agree, not necessary at this point.

You want to dyno your car in 4th gear.
