I HIGHLY suggest a 10.5 hot side though even if it's not mine and a retune. that car should make 350-375whp on e-85 with the mads that are already done and a better tune and hot side. you'll be in the 117-118mph range.

when they tune it have the rev limiter raised to like 8000 - 8100. so if you need RPM at the end it's there. those cams are gonna make power to 8000 anyway if you can get the flow out of the motor.
you see i thought since car from the factory making 270 hp@6.300 rpm whats the point to shift at 7000. i though shifting that late its just not helping much cause its not max tq.but probably im wrong and this dont apply on our cars with mods.
tuner says and i saw a lot youtube videos where evo 8 stock turbo on e85 making 370 whp.but i take your suggestion about evo 9 hot side.probably 400 whp achievable.
thanks for all the advices man.

Even completely stock you need to shift at 7200. With cams it holds the power longer in the rpm range. The torque is over by 5000. You use the hp that it making to push the car. The stock limiter is 7606. The torque gets you moving and the hp keeps it going. Rev it out, you wont hurt it. 7000 in 1st 7200 in 2nd 7300 in 3rd and rev 4th till you go through the traps. I bet you'll surprise yourself.

happens every time! just remember: If you never miss, you're not shifting fast enough.
