I think everything short of a Turbo Tuner is faster than Dinan as their tune is pretty conservative!

When adding the jb3 do you need to updrage the oil cooler or will the stock cooler suffice?

Stock cooler is fine unless you plan on lots of track time.

But if you plan on lots of track time then the stock oil cooler is not enough for a stock car.

what kind of octane do you run in your car? map 3 is great compared to stock but here in TX where theres 93 octane. i run map 7 if its low 80s and below and anything above that i run map 5. if you get 93 octane where your at specially in NY where temps are cooler map 5 as a daily driver is awesome and dinan stage 2 looks like a kids tune compared to your car then.
