2.76 open to 3.55 Sure Grip...expectations too high?

So far I'm doing pretty good; I got the tires right on, but overstated the intake duration @.050 by 3 degrees, which will not affect the Ica; So all my calcs are spot on. I even called the shift rpm within 100rpm. So, on a roll;

I was going to comment on how closely you nailed the shifting in post #31, because punching it in 1st around 25mph gets some good response, then mediocre performance until I hit higher speeds.

I also think I'm not allowed to visit whatever forum you've posted that in.

OK...it's not your 30" tires!

Yeah! 30 inches seemed pretty tall since I have 33s on my truck, but my ignorance in knowing metric tire sizes and not being with the car to double check the size led me down that path.
