okay so i recently installed a mbc my friend has the same one and it works perfect on his car so i doubt its the bc ...

so if i gas it all the way it will only hold 7psi once i shift it will spike to 10lbs but its always done that but lets say im in 2nd gear i gas it 75% almost all the way i will hold the 11lbs i set it at all the way to red line and spike @ 13 ..... so no mater what i will spike 2-3 psi more after every shift if im gassing it hard ...
but my question is why does it only hold the 11lbs sometimes and mostly only when stepping on the gas 75%....

do u guys think it might be my waste gate?? i have a hks i could put on but if thats it then i wouldnt need my mbc would i

lmk guys thanx!

MBC sucks, boost spikes are for sure going to happen.... MBC is a POS and anyone will tell you that... Invest in a greddy profec or something and geez... get a used one if you have to, its under 200 bux... Save yourself an engine rebuild....
