MHD told me that I should be hitting 18.5psi peak. Log is stating target boost is 15psi max.

Also, it looks like I am maxing out at 14-15psi.

Car is FBO with Inlets and VTT oem turbos with upgrades. Running stage 2+ MHD OTS map.

It's your engine noise reduction on?

All options, before flashing the map, are off.

you're not even hitting the 14psi target.

sounds like you have a boost leak and/or vacuum leak.

I think so too. I will have to do a boost leak test.

By the way, if I have a boost leak, does my WGDC seem high?

I'd need to see a log with wgdc after PID.

Sorry, what's PID?

might suggest replacing boost solenoid? See if there is a cyclic humming noise in the engine bay. if so, boost solenoid is failing and you're not hitting peak boost.

Boost leak check is step 1. Vac leak check is step 2.

Post boost leak test. Looks a little better? Charge pipe at throttle body was leaking. Tial bov (valve/screw on top) was looking a little. Only had an hour to check everything before work. Will check again this weekend.

Looks similar to my logs when I had a boost leak. I fixed mine (mostly) but have a hell of a time hitting target boost past 5500 rpm or so. I'm at over 5000 feet of altitude though, and have been told this is the reason. Either way, I'm seeing a lot of similar logs on the V7 MHD maps. have you tried switching to a V6 map? doubt that's the issue, but it would be interesting to see the difference in the logs

I did a third gear pull and now I am seeing timing correction on cylinders 1, 3, and 5. I chnanged the map to stage2. Looks a lot better than stage+

Here's the log.

I will try the v6 maps tonight. V7.1 stage2 feels/looks good. Where did you have leaks? I found some between the charge pipe and throttle body (used new o-ring from oil filter housing. They are the same) and one of the caps for the vtt inlets dv/recirc was loose.

Intercooler connections were my leak spots

Found some at the same spots and tightened up the tbolts. Car is running good but now my clutch is slipping. Damnnnn
