Having troubles tuning on a GM maf, car doesn't want to boost and lugs in lower rpms when taking off, it's a 3" GM maf with 560s idle is perfect but maf Hz are 5-600 at idle. If someone could share a tune for a GM maf or advice that'd be great thanks! Also my combined ft is 1-3 at idle and 10-20 at cruise.
 
I had the similar set up buy not for too long. Switched to sd and glad I did . I had too many isdues withe the sensor after a while.
 
3) GM MAF sensors are an ass pain. FWIW, this guy just went through some issues with his, and ended up ditching it...I'd consider doing the same to be honest: http://www.dsmtuners.com/threads/maft-v2-vr4-tuning-first-attempt-help-please.511093/

@COVR4355 can give you some honest feedback there...[/QUOTE]
LOL...GSTwithPSI is not kidding. Really my only choice was to ditch the MAFT-dumped nearly 12+ hrs into screwing around with tuning the thing. Went through all of the required steps...GST and others have set up a wonderful to do list that is pinned on the top of the Tuning and Management forums-and yet had upwards to 40% swings just to get the AFRest to line up and ran like pooh :(
Speed Density so far is far much easier and lacking all the gremlins I had with the MAFT.
Best of luck to you good sir and if you plan on keeping the MAFT the following two are incredible valuable.
