Can someone tell me the ingear boost figures for a hlm 304 ?

i'm starting to get very piszed off with the car now, with or without the remap, with a mbc or not it hits 10psi in 2nd and 3rd gear, with the traction off it wont even spin the wheels in first !!!

ive changed every single hose on the car and bought proper clamps for the rip kit, ive adjusted the actuator so it is halfway over the hole, only thing left i can think of is a weak bcs but i still got the same readings with a mbc,

talk about pulling your hair out !!!! next things going to be a can of petrol and a match......
