My mods are in my sig.. I'm not as of now making theses numbers.. I think I'm making 300whp when should be making 360-370.. The tuner said he couldn't figure out y my car isn't making me more..

Could it be that I have a small 2.5" pipe between the 3" mid pipe and my 3" cat back.. Think that could restrest u 50-70whp

N also how much does a exhaust muffler restrect u?

 

have you done a boost leak test?? also I would switch straight to a 3.0 all around however that won't e the cause of you making 50whp less.

 

If your tuner can't figure it out, take a drive to Buschur Racing they'll fix it for you 100%.

 

yea just need a special peiace for that one section..

Thanks..

Anyone else?

bump anyone?

 

Log your setup and review with a tuner. I suspect boost isn't as high as it should be, but dangerous to guess when you can log and know for sure.

 

you should def be in the 360 range... I have everything u have and i have hks272's which are known to be way less aggressive as the kelfords... i agree with you swapping that 2.5 pipe but 50hp is alot.... good luck...
