so far so pretty damn good.

2006 cobalt (no more turbo)
m62 2.7 pulley, E85, 79lb/hr injectors, 4-2-1 longtube header, airbox mod, stock catback
1998 Trans am 5.3 iron block 317 heads 88mm turbo e85 105lb/hr injectors, twin 255's.... build in progress
2014 wrx mild tune 18psi pump gas
I set the "Boost Test Enable RPM" to 7000 rpm for both 60 & 100. Then turned the MBC til we got to 24psi and when I went to do a 4th gear pull on the highway, but after a few secs ALL Boost was cut...... help please....

I got some strange results:
I'm running 25psi on my Solstice GXP with 16g turbo using the air load torque tables to control boost (modified GMP2 tune)
Since I have already run 28psi with this tune and did not want to go higher, I went lower.
I set the "overboost Allowed Error vs Desired Boost" table allowed error values to 20 at 7.3 thru 17.4 in an effort to induce limp mode. The car would not "limp" So I set these values to 18 and still no "limp" mode? There was no difference in performance after at least 15 boost runups in 2nd 3rd and 4th gears. No error codes either.
What's going on?
if you saw P0234 please contact support, if you didn't we need more details, codes etc.Originally Posted by rtkjadams

odd, we were running 26.2psi on a gt3076 overboost test set to 8100 rpm. no underboost or overboost codes thrown yet all week, and believe me we tried lol. 5th gear 2000 rpm pulls multiple time to try and trip the underboost, nada.

that would of def. set an underboost code because I fought that with my setup
So HPT at this time can't raise boost by using the ECU in a 97 GXP? You would need to use a MBC? Is this correct?
Uhmmm... i think were talking about different ECU's there buddy.
Sorry 07 GXP, 97 did not exist
Oh haha! I was thinking GTP for some reason.
No codes..... what kind of info do you need?

According to google yhou have an antivirus problem that needs to be fixed, its not a software issue on our end.
It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
anything in a log that might help me understand why it is being cut. ie. throttle closing, BOV, anything that will help me.
These new params only address the P0234 Overboost and P0299 Underboost DTC's
