m20 turbo spark blow out

[JoMbO808]

hey everyone,
could someone help me out. my turbo m20 spark is blowing out approx. at 4500-5000rpm with only 10lbs of boost. my parts beside my bottom end of the block(2.7block I-head)

vacmotor sports turbo cam
garrett t3/60-1 turbo
id1000 injector
areomotive fuel pressure regulator
diyautotune 6-tower coil pack with the quad spark module
ngk v-power spark plugs(bkr7e11)(5791) gapped at 0.025
turbo-smart e-boost2 boost controller
that's what I can recall so far.
anyone experience this or knows whats going on? this is a reason why my tune was stopped.

Mahalo everyone!

Does it blow out, but continue to 7000RPM?

4500-5000RPM is usually where a bad or badly positioned crank position sensor makes you hit a brick wall on the RPM range. Check to see if it's screwed in tight and appropriately positioned.

If that's dandy, try closing your gap to .022.
A lot of m20 turbo's, including me, run bpr7es gapped at .022 - .025 without blowout 17psi and under.

Remember though, the tighter the gap, the worse your car will run at cruise/lean conditions.

the blow out will continue all the way through. I have check my timing multiple time. checked if the screw is on tight. but yeah imma try your set of plugs

What are you tuning the car with?
What's the AFR reading when spark blow out occurs and timing?

so I used the plugs recommend, my concern is still there. when hitting boost my spark blows out, rpm would be steady and no speed will increase. any other thoughts????

Sounds like a setting in MS needs adjustment.

Have you adjusted the accel enrichments settings? If your fuel VE MAP is good, turn off the EGO control.
