05 GTO tune help
I was wondering if it would be worth it to either have a mail order tune or have it dyno tuned? Also I noticed some hand helds like the Diablo and was wondering if this is something a novice can use?
I live in CDA, ID but Spokane Washington is the closest real town. Anyone know a good shop or have advise on picking a good shop to have a dyno tune done?
Thanks for helping a noob.
You wnt need a Dyno since you just have bolts on mos. Once you get a cam, ported intake etc etc you can go for the dyno.
