6x.018 stick hot rod pump
Fass 220 quadzilla 4K
Head studs ported polished heads
Colt stage 3 cam

So Idk if I am boosting my full amount of not but I only boost about 50lbs in 5th 57lbs in 6th I figured I would be more close to 70 idk what the problem is but I feel like should boost more and I ve checked for boost leaks and I don't have any. What do You guys think?

How are your egt's? So long as they're being kept in check, your amount of boost is sufficient, so beyond that it's just a number.

Also don't forget, the better flowing the head/cam combo, the lower the boost will be for a given HP level.

Boost is largely a measure of flow restriction.

Since you have a good cam/polished ports, I would think your boost levels would be lower than a typical stock twin configuration.
