    not entering boost enrichment...please HELP

    Hey guys! Just want to start out by saying thanks to everyone who has taken the time to give advise and share your knowledge. I have spent hours reading and searching a cant seem to find any answers on this. I have a 2003 Escalade EXT. I installed a 2.3 whipple supercharger,60 # inj, a transgo shift kit, and a boost a pump set to 100% all the time. Its a stock internal lq9. I have done the 2 bar upgrade and followed the instructions on the hp tuners site, and yes... I got a wideband before doing anything!!! I notice when I get on the throttle it will go into pe mode, but as I go into boost it starts to run very lean. I do have a fuel pressure guage and it will hit about 58 at 0 vac and rise as boost rises. Any advise on what is missing or anything I am doing wrong will be appreciated!!! Please feel free to check out everything, and let me know!

    it doesn't look like you are running speed density mode.

    You need to fail the MAF or unplug it. Set P0102 & P0103 to "2 - No MIL"

    I'll do that first thing after work! I didn't think it was an issue since I'm not maxing out the maf. Thanks for the help!.

    I tried to unplug the MAF one time and the check engine light came on and the vehicle barely ran so I had to stick with "failing" it. But it still showed that it was reading normal air flow on the datalogger. Not sure if I set up the P01012 & P0103 up correctly though.

    I tuned a turbo cts-v and it didn't have an issue with going into boost enrichment. We ended up taking the maf out after we started maxing it out. I set it to no mil and no error reporting. Is this wrong?

    If you have no error reporting in will not enter SD

    you must have codes P0102 or P0103 set for the PCM to run SD.

    Set them both to "2 - No MIL".

    To set these code you either unplug the MAF (sets P0102) or change the MAF Fail Frequency to 0 (sets P0103).
