not that I dont its just acting wierd...the turbo works AWESOME btw...the head not so much...i ended up just rebuilding the existing head...cost my 700$ thru JB precision...but back to the waste gate. I set the stock bcs back up...took out the mbc and in 1st and 2nd gear lower rpm....WOT I hit about 8-9 psi...BUT i dont know if this is boost creep or what...after 4k rpm the boost creeps up as high as 15, 16 psi...and it really pulls hard...but I dont know why I have to wait for the higher rpm for the boost to go up higher...I thought stock boost was 12-13... which has me asking why I only have 8-9...then jumps higher to 15-16... :S the 14b was a steady climb from 0-15....

When your boost jumps does it spike then settle to whatever setting you have? My 16G boost slowly increases then picks up a little fast past 10 psi, mind you my is not set properly so I dont hold the acelerator down constantly (dont want any problems!) could just be boost creep and boost spiking. Check for leaks make sure all hoses are properly connected and such.. WHen you had you mbc put in did you leave for bcs attached?

literally less than 15 bucks at home depot after everything... i got the valve stem from cdn tire, just bought the cheapest tire inner tube for a bike, and hacked it off... and glued the shit out of it with bulldog,

this is what i found when i did mine
