. I don't think he knows what a 3.73 is lol
But then again I only have cai and 78mm tb/p and my car pulls like raped mule in third...
Haha. What is this "3.73" you speak of? :p
I was referring to the gear ratio in the rear differential, OP. The steeper the gear the faster the acceleration. Stock GTs of our years come with a 3.27 gear ratio which is a decent driving gear for MPGs but it falls on its face in third gear and above. Steeper gears like 3.73, 3.90, and 4.10 provide much greater acceleration at the cost of a little less drive ability and mpgs. Gear ratio is essentially the relation between how many times the driveshaft rotates per every one revolution of the rear tires. So a 3.73 gear means te driveshaft will turn roughly 3 and 3/4 times for every one rear tire rotation. The more the driveshaft turns per tire revolution, the higher work is being done by the system therefore less energy used to accelerate. Less energy means more is applied overall so it acts as if you just added 50rwhp to your car(at least it did with my 4.10s).
Now that's a way to cure your "dud" acceleration.
If your car is not accelerating because there is an actual problem you may want to check for vacuum leaks and/or clutch slippage.
