Default 0 WGDC, High Load, Low Boost

i am having a strange issue. back in november i was slowly upping the TRL in each gear to achieve my boost targets and was getting pretty close. i started doing some logs the last few weeks and 2nd and 3rd gear seem normal. however in 4th and 5th gear my WGDC almost immediately goes to 0% at WOT. also im barely seeing 14 psi even though the calc. loads are in the 190's. i reflashed to an older map today and did a few pulls and im having the same issues. anyone ever had this type of situation?

Ive been having the same problem, im set to run 18 psi but I only get maybe 12-13 with 190-200 load and 0 wgdc... that and my MAF sensor is maxing out around 5500 rpms then the engine cuts and my afrs dip into the 9s, im switching my aem intake to a CPE in the next week or so hoping that might help but Im thinking I just need a larger MAF housing...

08 currently running AEM CAI, CPE TIP, GT2871, Forge BPV, COBB DP, Vibrant exhaust with ptp fp internals

When do you guys feel you start seeing boost drop?

I have not noticed much difference in the 60's but am unsure.


60's is cold here.
