Really? 1:1 ratio or closest... hmm... I looked up the C32 and it's gear ratios are as follows...
Gear Type 5 Speed Automatic w/ Touch Shift
Final Drive 3.06:1
1st Gear Ratio 3.59:1
2nd Gear Ratio 2.19:1
3rd Gear Ratio 1.41:1
4th Gear Ratio 1.00:1
5th Gear Ratio 0.83:1
So, presuming it's the same transmission... maybe that WAS the problem!
Thanks Derek! I think I'll call Paul tomorrow and ask him if it's supposed to be that way on the automatic too... if so... maybe he'll give me a discount or free retest.
EDIT: Funny thing, if you multiply the HP numbers I got on my last dyno run with the second gear ratio, you get the stock HP numbers for the C32 AMG (354 HP).
