boost fluctuation with Zex 53900??
I have just recently rebuilt my motor and have been using the ZEX 53900 cam. I noticed that during the vtec switch over i loose a little boost. For example, while in second gear WOT, i'll get 10psi no prob all is dandy. When i shift into 3rd it will climb up to 7-9lbs and fluctuate there till i reach higher RPMs... like 6000 RPM and up. At first i thought it was something funky with my HMT boost controler but it never did this before.
its annoying as hell... anyone else experience this?

today i went through and checked all of my couplers for leaks...
i think ive narrowed it down to dirty air filter, although its not that bad, or shitty boost controler.

so tonight i took the HMT boost controler apart, which consist of a "t" and nipples on each end, spring and ball bearing... i disasemble it, put it back together and guess what? everything works fine. no more boost fluctuation. ------- gremlins i tell ya...
p.s. i noticed about a 200whp difference with the cam!
