No power up top after intake and more

It gets up and goes from idle to 3500ish...then it just flatlines and doesnt pick up power at all. I put on Trickflow street heat upper and lower, BBK adjustable pressure regulator ( no pressure gauge but it runs ? ), SN95 fuel rails. JLT Ram air, Professional products 75mm TB and EGR, Trickflow tall valve covers, trickflow 1 inch spacer, 180 degree thermostat. Also has just recently doesnt want to start, have to keep letting it turn over until it finally fires up. Acts like it doesnt want to start.

Anytihng ?

Yeah, it was deff. fuel. I checked pressure today with my gauge at work and i was only running 19-20psi.

So i jacked it up to 39-40psi. Runs like a charm. Pulls hard bottom and top. Which suprised me for a Trickflow. I was taking it back to the shop and i was in third at 3600rpms and i jumped on it and it broke loose. So fun fun. Except that was the exact moment my waterpump seal blew out and i was gushing coolant all the way back. Thankfully i made it back to the shop. So right now its apart in my driveway ready for a new pump, and im waiting on my a/c delete to come in. And the smog is already off. So....yeah. Still havent nailed the whistling noise from my intake ( vaccum leak kinda noise. ) Removed the upper and no signs of a leak in the gasket. Im gonna use rubber vaccum lines and redo all of them and get rid of the Ford hard plastic lines. I dont think im pulling so much pressure on vaccum to colapse them. But i guess i'll find out.

So it was fun for a matter of 10 minutes beating on it....now its broke again. haha.
