I know this has been posted a million times but

DRAG MANIFOLDS SUCK BIG DONKEY DICK. IF ANYONE IS THINKING ABOUT GETTING ONE.. DONT!!!!!!!!!!!!!!!!!!!!!

I just changed to a inlinepro SS. Guess what NO MORE BOOST SPIKES.
My blitz SBC i-D can actually regulate my boost now.. WOW

I wasted 500 bucks on the dyno with that crappy manifold.
Cant wait to hit the 400whp club now
Hit 340whp@15psi with the crap drag spiking.
Hoping for over 420 with the inline @ 20

Thanks for letting share my fustrations
