That was due to SU's fail boost tubes. All is fine with the stock tubes .Unless you're Sho. lulz.
But interesting point, Mr. Kulish.
I obviously havent done any track days or autox...but upgraded top mount vs stock tmic, im seeing lower BAT's at cruising speeds and WOT as well as sitting in traffic.
What i will say for evan #2 and aj, watch your fuel pressure with the upgraded intercooler if you dont have HPFP upgrade. My stock pump would drop to 1000psi or less at any boost level over 16.5psi.
These teeny tiny k04's dont really lag though unless you have a lead foot at low RPM's, but we all know not to get into it until around 3k rpm anyways.
I dont know how hypertech targets boost, but with the SU TMIC, Test tipe, CAI, and HPFP i was overboosting until a buddy helped me out and lowered WGDC in the earlier rpms due to the increased flow. Running the same stage 2 cobb map with the stock intercooler, i always met boost targets which was 19.5 tapering down to 17 by redline.
