Ok but did you guys go from tuner to tuner plus headers? I swear my bottom end torque has decreased. It doesn't have the same response on the line. I know bane has no cats but nickpick has cats and 7/8 so he might have a little more back pressure than me.

It's too much for me man! The raspiness is ridiculous WOT but that's top end. On the bottoms end it feels empty and it sounds like metal rattling. I know I know a lot of guys like this uncorked raw sound.

Maybe my tune is off? I called mike at 5 star and he says it's normal to lose bottom end with the larger diameter header and that cats and a resonator would add more back pressure.

Id be happier if the sound matched the performance but right now it feels like sound went up 10x and performance decreased back to stock

Haha. Yea the gf doesn't like it but I blow by all the little cars and the "regular" to truck and make her laugh.

With a tow tune it has more torq and I can feel the wheel hop. The only time it didn't perform as well was before I put the magna packs on. Now wayyy better and shes quick to me.

Mine is lopping and gargling at idle like it's gonna die but you guys said my rpm is normal. It just feels like there is no bottom end! And then all of a sudden a ton of noise and the truck isn't even moving like it used to

Yea mine did that too. It lasted for about a week before I think the computer recalibrated or the fact that I put mufflers on it.

It scared me and it felt like it was gonna stall every time I went up my driveway and let off the gas.

Do you run pipes all the way back? I had it dumped with no mufflers under the pass seat, and then I dumped it with magna packs. Once I put the mufflers on it stopped. But I have pipes tucked high and exiting in the stock location and she runs like a dream now

Are you experiencing any similar issues?

 

[BANE]

nope not at all. but i dont think adding the resonator will help?

Then maybe you just need the brake in period. How long have they been on the truck?

1 7/8. And I ran the stock tune for the first 2 weeks without a check engine light before I put a tune on.
