i have a 2000 Gt with a CAI, borla exhaust, steeda under pullies,and a diablo predator. Igoing to put on long tube headers and an off road h pipe. Would i have to retune my car with the diablo predator after i put the headers and the off road h pipe or no?

 

was the tune you loaded just a generic 93 octane tune or something set up specifically for your car? if it was just the 93 octane tune you'll be fine.

you can just install them and revert to either the premium gas tune or stock tune if you have a custom oneand be fine.

 

no it wasn't specifically set up for my car... just the tune that came wit the predator.

 

yeah if it was just the generic premium tune then no worries unless you start using 89 octane.

 

ight no doubt thanks for the info

 

You'll be fine with the predator tune.

 

get rid of the underdrive pulleys!!!!!

 

why would he get rid of the udps

 

yeah, i probably wouldn't buy mine again, but they are on, and they do help a little bit...

 

why should i get rid of the underdrive pullies?
