90TGP Posted March 16, 2003 Report Posted March 16, 2003 So does anyone with a 3.1 have an underdrive pully from http://www.fastfwdperformance.com??? If you do, post some feed back! Quote

ctx46 Posted March 16, 2003 Report Posted March 16, 2003 I have one on my 3.4...... I noticed a bit more power out of it with NO negitive side effects, the throttle feals allot more responcive than it did befor I put it in..... sorry, Im not a 3.1 though, I would imagin you would gain a bit more low end....... but thats my guess....
