hey guys this might sound stupid. I wanted to know if i were to install underdrive pully's on my car. Will i need to get a tunner to calibrate for the change in the belt speed or can i run them without recalibrating? I need to know so i know what to buy first currently all i have for engine mods are cai and a catback exhuast. apreciate any help you can give on this. also real quick what company do you recomend for pully's? thanks

You dont need to calibrate anything for pullys.

don't need anything. Might want to advance the timing while your at it.

Steeda for pulleys

Emann0007

steeda timing adjuster and pullies, do both at the same time, makes it easier to "feel" your money at work!

Not a borla fan, but the steeda exhaust is just "custom" tuned borla system. The one I heard wasn't very loud but not so uggg sounding like the borla systems I have heard.

Thank you for the info. I have one final question if i get the pulleys and i am planing on supercharging my car in the near future will i have to remove these? if so then i will be looking at the predator for Christmas. Thanks

Hey... if you need a timing adjuster I will sell you mine. I had a guy that said he wanted it but has yet to send me the money or a return email. It costs $149.99 online + shipping. I will sell you mine for $100.00 anf I will ship it to you for free. Let me know what you think. Post here or email me @ Jdanielm1@Yahoo.com.
