Boost Leak??

[Omega412]

Im hitting no where near my peak boost, a previous log showed me hitting 7 psi at peak, but now im only hitting 5.

I’m no expert but it does appear that you have a leak…also your timing corrections on certain cylinders seem bad..looks like you have the OE FMIC as IATs climb sharply..

STFTs don’t quite match…

Would be good to see both waste gates duty cycles logged..

The connection coming out of the cold side of my intercooler completely blew open so that's that. How would I go about logging wastegate cycles?

After looking at a previous log, there was only slight timing corrections occasionally in cylinder 6. Then my boost dropped three psi and all six cylinders started correcting.

Obviously if you re-run the logs you can then see if the timing corrections are now acceptable…the MHD logging offers many parameters..you just select the two wgdc paramters at the expense of one of the other parameters..since you’ve discovered the fault it’s probably now irrelevant..I was suggesting it as part of the troubleshooting
