Ive had a chance to play some with my turbo setup . Keep in mind that this is a just about stock motor running 8 pounds of boost and 3.55 gears and like zombiestang said as soon as I hit the gas im also making boost . 8 pounds of boost by the time im at 3500rpm. The only problem is there is sooo much TQ that the tires want to break free as the RPMs climb in 2nd and 3rd. On the hwy the gear seems fine 2000rpm im running about 75mph. All and all i am glad i went with the 3.55 i think its a good allaround gear.
