ok so put on the test pipe and the idle dropped. Where is the best place on the engine to fix the idle instead of taking it to a shop or adjusting it on the throttle. I heard if you adjust the idle on the throttle all **** breaks loose.

 

What is it idling at?

 

at about 200-300 it used ti be at like 500-600 which was below anyways after i put on exhaust and header but its a dc header and 2.35 exhaust

 

Maybe you have an exhaust leak somewhere????

 

well everything is brand new and everythign was sealed when we put it on in my friends shop with everything torqued down
