You'll need a new tune when your CEL comes on. You got it from B-speed - right? Won't he update the tune for free? (turn the o2 sensors off)

 

the tune has the sensors already turned off. brenspeed told me no update required.

 

Cool, same set-up, love da sound & loud when you want it

 

Congrats! No need to reload the tune..... You might have lost a tad of torque way down low but made up for it on the top end. An offroad H with factory mufflers is a good sounding setup.

 

I hate losing torque Did you see my torque? It is missing and I can't find it??? PM me if you find my torque please. I better get it back with some UD pully's or gears!

This install has given me the confidence to try pully's myself.

 

The ultimate solution for torque is another bolt-on mod........
