Hey,
Just got back in the DSM game after 12 years.
Running Speed Density 1G ECU ECMLink V3
Billet 20g in a Machined EVO III Housing
AEM 3.5 BAR MAP
GM IAT
FIC 750 CC injectors
Rewired 190LPH >>> YES I need a 255
FUEL LAB AFPR set to 43.5psi
I can cruise around and drive and get into it a few times and everything is fine.
Then down shift and it starts getting into boost around 3700RPM is goes to hell for about 10-30 seconds RPM (12.5K) and AirFlow then back to normal and it just keeps doing it then finally recovers. I logged everything it would let me.
Please see the attached log the issues start just after 380 seconds. Trying to determine what may be causing it. I have a spare ECU spare Coils and CAS.
There is a clean 2nd and 3rd gear pull at 294 Seconds to 302 Seconds
And another 3rd gear pull at 338 Seconds.
Looks lean at between 11.7 and 12.1 Denver tune brought to Utah and its is only 4400" here but the issue was present before.
Thanks,
Dustin
