Message	First run with controller off so about 14psi = 383.23hp 341.04 tq second run with controller on low and lowered the timing and gained 10hp (still base boost but controller gain and all set) third run at 18psi and timing retarded still = 374.61hp 374.53tq So I am lost about whats going on! Before dyno i did: 1) fixed the vacuum leak on passenger turbo 2) ran boost leak test showing small leak on drivers side same problem 3) checked plug and gap .040 4) changed oil (used 20W 50 castrol syntec with lucas) 5) ran seafoam 6) checked timing (set initially at 15) Need some help here I think!!! 1990 300zx 2+2 TT White w/ Blue Pearl Stage IX+ "She may beg, she may bleed, she may argue with her logic and mention all the things I'll lose, that really have no value, in the end she will surely know, I wasn't born to follow."
