How exactly do you have it setup as far as under the diag. section with the MAF codes?

Mine stumbles but doesn't die. Always wondered if it was normal.

It is likely the idle airflow that needs work... could be other things as well...

You have to have the codes for the MAF set to non-emissions, they can't be set to not reported or it won't even start...

Mine does that as well.

After flashing a tune you need to turn the key all the way to the off position before starting it up.

I've had this problem ever since switching to the new version of hpt. SD, stock os, makes no difference. Just takes a little while to clear up.

do a search for russk-Idle-Airflow.cfg and learn how to use it.

Mine would start and die multiple times after a reflash until it would finally set the MAF codes, I searched and searched and asked here and hp tuners forum and no one could help me out. I finally figured out Engine>Airflow>Dynamic>Dynamic Airflow>"High RPM Disable" was set to 4000rpm stock, I set that to 0 rpm and now it starts everytime after a reflash, it does stumble for a second intill the MAF codes set, I think that's normal from what I found.
