Headers untuned?
I recently purchased Kooks 1 7/8" LT's with a catless 3" x pipe. The problem is that my car is already tuned on stock manifolds with a P1SC blower on about 7 lbs(4.25" pulley) motor is an LS2. Has anyone ran untuned on a blower car after headers? If so were you able to give it hell or did you have to drive pretty conservatively until you retuned? I plan on modding more in the spring but don't wanna pay to tune twice if at all possible.

Could cause major trouble real quick. Get the retune!

Read somewhere that opening up exhaust to flow more, will lean out AFR and if this case would be major problem with a S/C
