yep i got my 2.9 pulley in the mail and had it installed in about 25 minutes! wow i can sure tell a difference....any idea on how much hp that would add compared to the stock 3.2 pulley?

better tune that one... its great for more power, but more power = more likely to damage a piston

see i asked this before...do i have to do anything with my split second system now?

by **SC V6** » Mon Jul 17, 2006 8:08 am

get it tuned in properly... I'd just be careful, I've heard of many people blowing their motors on here. You have headers?

you just need to add more fuel...do u have a wideband?

sorry man i am new to this, not sure what a wide band is???? what exactly do i need to do? sorry for my ignorance!

with all my supporting mods, does 1.5 psi really create that much of a problem?

by **SC V6** » Mon Jul 17, 2006 8:17 am

wideband is refering to wideband o2 which is needed for tuning the whole fuel map. hit up a dyno and get it tuned in

isn't this what the split second fuel calibration deals with?

by **SC V6** » Mon Jul 17, 2006 8:29 am

yes... you would be surprised with our motors how much an extra 1.5psi can do

by **Wang2k** » Mon Jul 17, 2006 8:34 am

A wideband o2 sensor goes in your exhaust seperate of the other oxygen sensors. It hooks up to a digital display inside that shows you your cars air/fuel ratio. You then use that info to add fuel at lean rpm/load places. With your SS FTC it controls part throttle as well as WOT so u have to tune the whole map based on different circumstances

you are really helpful! so can i do this with my ss ftc? or do i have to take it to a dyno shop?

well.. under closed loop (WOT) your S.S. will take over completly, under open loop (anything lower than 90-100% throttle) your ECU will change things, you S.S. will still have input to the ECU, but the ECU will adjust things at will.

You can get a wideband o2 setup which allows for a gauge that can be hooked up inside the car to see what your running for air/fuel ratio. To get tuned in, the easiest is to go to a dyno. Street tuning is more complicated.

thanks man you guys are great! so do i need to do anything with my ssftc? can i hook my ssftc up and see what my f/a ratio is or if i am running lean?

by **SC V6** » Mon Jul 17, 2006 8:50 am

your split second won't show if you are running lean or not.. you have to go to a dyno or somewhere with a wideband o2 to see what you are running, then dial it into the S.S.
