well i made my own MCB. as stated here. http://www.geocities.com/chmwatson/FAQs/mbc.html
my psi goes up to 9 or so then falls to 5 once the turbo has reached the end of spool up. get what i mean. ill give it full throttle it will go to 9 then its drops to 5. haha w/e it happns could it be sumthing else like a leak? but wouldnt a leak not allow it to go to 9 in the first place? -------------------- |

right now its at like 7.5 psi in first through 4th then 5th gear brings it up to around 8.5 it weird. turbo is alot louder. bov is louder. and the car is quicker. love it. whil i was tuing hte MBC i went up to 13psi. was amazing. but i was ther for a fraction of a second before i let off the gas.

there is more load on the engine in 4th and 5th its very normal to hit higher boost in those gears, especailly with a MBC btw i made a similar one for my friends 240z with a 280zx turbo engine swap. except the one i made is more simple and can make for much higher boost levels than stock, lol, but of course i lengthened the wastegate actuator rod so that it will run only like 3psi with out the mbc now if only we can get the damn engine to start. -------------------- 1994 Celica GT4 WRC Edition

What preset 9? 3s?
Just turn the boost down and it'll go down. -------------------- |
