What? No Headers?

Sounds good to me. I just ordered a similar Wester's tune my my ride.

I figured the headers would take some power from the low/mid range and move it too high up in the rpm's. I dont use power in the upper rpm's, mostly low to mid for off roading and a quick gettaway every now and then. Thanks for your opinion though.

aWhy would you think that? Helping the exhaust gasses escape will increase performance thru the whole range. I definately feel it in the low end....ah, that sounds funny but you know what i mean.

 

Cant wait to get the pcm tune, my truck kicks butt now!
