Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

1999 Grand prix... Looking to run a 3.4 pulley



Same with Nixon, mine says premium only on the inside of the gas flap haha. Only use 93. OOOOOW im excited, i think i got everything down now for the modding. Thanks for the info guys, sorry for the thread jack.
 
dont wanna highjack the thread, but do you think I could run a 3.6 pulley w/o headers or would that be askin for problems.
