It Seems To Me That My 4.8l Ext Cb Chevy Got Noticeably Better In Hp And Throtle Response. My Question Is Has Anyone Else Experienced This Mod With Basic Stock Setup.....flowmaster Exhaust Only

 

How long have you had it on & how many miles?

 

HD what does your truck sound like with the proflow?

 

It seemed to give it a boost. My one time at the track was after I put it on.

 

I Think That It Has Been Maybe 200-300 Miles. I Just Took The Truck Off The Road.

 

Yeah that was the first thing i had on mine, i noticed it felt a lot better up top in the RPM's and gas mileage increased

 

That's pretty good. I noticed that when I first put my Airaid on it felt stronger, then the computer relearned and some of that SOTP feeling went away.
For Gobblergetter: the Flo-pro has a real nice mellow tone overall,sounds stock over about 2200rpm, no drone at all, & got a little louder after about 1000 miles

 

Yeah I Recently Bought A 2002 Hd2500 Regcab, With And 8.1 In It....lots Of Stock Hp. I Can Only Imagine What Will Happen When I Get The Cai And The Exhaust On It!!!!!!!
