#805, "RE: How much did the Final Drive help?" In response to In response to 0
I noticed a good improvement. I pulled alot harder. I bet it helped you out some, but since your boosted I think it would be harder for you to notice since your car had so much balls before you did this. I don't know if this is in your plans or not, but I think the shift kits is the final piece to the final drive gears. It's like a P&P intake to go with a BTB. Not power wise but one just helps the other work better. This is my observation anyway.
