You think it runs strong now push that puppy up to a real 15 pounds of boost. Or pulley it for 20 and waistgate it at 15. you get your boost early
Now im excited lol time to push her asap then

A boss or an 18 are the same gains
Yeah i seen that, i'll be happy with either, thanks boss

Boss intake on a S550 requires lowered motor mounts or an aftermarket hood. Stick with the 18 mani for the S550. The gains between the boss and 18 mani are the same

I'm on a P1SC-1 stage 2 kit with Corsa cattless long tubes and cat back. With the 4.00 pulley I see 14-15 lbs. Measured by a mechanical Autometer boost gauge. This is around 7,500 - 7,800 rpms. Stock 2015 intake manifold.

you should really get an 18 manifold on that thing. I think you’re not really getting much benefit from revving to 7800 with stock manifold.
