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.

yeah i did the same with my actuator rod. i ran stock 5psi. cool about ur friends car. so yeah point of thsi thread i guess ucan make ur own for $12 instead of paying for one.
