What sort of config is this? Looks like boost for K04's, stock fueling, 5bar.

You are correct sir. GIAC 3- (Moss Tuned file). Tip. Does everything look ok?

If you have GIAC 3- file, should not need a MBC.

Since I now run test pipes and straight pipes, I get a little overboost.

OK, make sense. But do you get overboost TC (throttle cut) with no MBC? If not, then MBC not needed

Yes, I do get overboost TC. Verified by taking LOGS. TB Valve Angle close on spike.

Default You can dial your MBC boost up another 0.5 to 1 psi and be OK. Most overboost happens on intial
boost ramp at lower RPM. Ran GIAC 3- for 1.5 years or so on 6MT. Loved it!

We both know that's not necessarily the case Bruce.

Yes Brian. Yours also was a 3- TIP. Mine was a 6MT and was fine (no MBC). Pattern?
