thanks for the help with the computer upgrade. i just have one more question. can i get a power pulley kit w/o upgrading the computer? i don't see why i wouldn't be able to but i just wanted to make sure. thanks again

 

what ecu did you get? you should be okay but don't quote me on that as I don't know what you are running and what mods u r running

 

Ususally the ECU upgrade is to help with the Air/Fuel mixture. When you change the air flow of the car, the ECU can only compensate so much so you need to have it reprogrammed or changed. Since the pulleys aren't directly increasing the air flow, you should be ok.

 

The underdrive pulley won't affect anything but weight on the eccentric shaft. No need for fuel/air adjustment. I have an anodized red Unothodox Racing Underdrive pulley for sale if you're interested.
