TP limited at idle on e38 speed density tune

[dieselmd]

I have a 2008 G8 procharged running a 3 bar mafless tune. At idle, I can't get over 19.6% TP. Tried lots of things with no luck. Only became a problem after losing the maf. While cranking, it will open up to 25% but will quickly come down to 19.6 which is causing me some idle issues. Just wondering what I've overlooked. Thanks!

give it an air leak (ie purge disconnect off manifold) and see if that helps your idle issues...seems like a hell of a lot of air requested for idle?

G8's tp is offset from other os'. I figured this one out though. Efilive doesn't have the necessary table to fix it. Apparently the g8 os has a max idle area fail table that limits idle air flow when a map or maf fail is detected. Hptuners to the rescue on this one.
