So that has alot to do with you gaining so much but still thats alot of Torque to gain
My code does go into open loop,but i am hoping the tuner wakes it up enough so it keeps me happy until i have enough money for 4.10 gears!!

Right On Bluegrass

Bluegrass you are right on the money
back in the 60's one of the fastest set ups from street sign to street sign was a 283 with 265 heads.

99% of the world would put a big cam , a way to big 4 bbl and dual exhaust.
just killed volumetric efficiencey from idle to 3000/4000 rpms.
The little 265 heads due to their smaller runner volume would really pack in the fuel air charge-of course by 4000 rpm the engine would fall over on its nose.

I explain horse power VS torque like this.

If you have a german shepard and a rat terrier and have each dog move 200 lbs. of dog biscuits 100 yards the german shepard will move it in 1 trip taking 10 minutes. The terrier will make 50 trips in 10 minutes.

Both have done the same amount of work therefore the same amount of horsepower has been expended. The shepard has more torque and the terrier rev's higher.
