I have a stock redtop with a MBC, FMIC, 255 FP, turbo back 3in' exhaust
I set the boost to 10psi which works fine, but for some reason the boost spikes upto 16psi only in 2nd gear. up shift or down shift.
I though that it may be because i ran the MBC to the cockpit and the extra distance causes the MBC to lag on controlling the boost.
i did a boost/vacuum leak test and everything was fine.
can anyone verify this or help with my prob. I also have hesitation at 15% throttle. <----upgrading spark plugs soon to see if it helps
