I ran my best ET ever at HRP the weekend the track repopened after winter break.
I agree with u, its just the weather. Sierraboy what u expecting out of headers. Two tenths is whayt u should see.

I have OBX LTs.

It just seems like for people with stock cam trucks, these long tubes have too big of primarys for stock cam fairly stock engines. Although I didnt notice any power loss down low with my OBXs I dint notice anything up higher either. But then again I havent dynoed or went to the track to verify, but as far as I can tell it didnt do anything.

Did you get the truck tuned for em?
I'd say your buttdyno is just off. You should have had a very nice midrange-upper rpm jump in power.
Oh and i have a stock cam truck with pacesetters and e-cutout. Truck goes faster with the cutout open and has ran a 13.7@99 a handful of times now.
