Tuning MAF
Has anybody tuned with zzps 3inch MAF housing, if you have, have you ran into issues with code p1101. And did you have to recalibrate for the larger housing.

See where I'm going here? You may want to either pay someone who knows their way around hpt to do this for you or pull up a comfy chair and do some serious reading on the hpt forums. There's a lot of good stuff to learn on there so just read up a bit before you get too crazy.
There even more to it than this than what typed, but this is basically the cliff notes version of what needs to be done. I hope this helps you a bit, or at least gets you in the right direction.

Oh yeah, I forgot you mentioned that.. lol..
here are the steps from GM's service site that are points to check when this code is set
• A restricted or collapsed air intake duct
• A misaligned or damaged air intake duct
• A dirty or deteriorating air filter element
• Any objects blocking the air inlet probe of the mass air flow (MAF)/intake air temperature (IAT) sensor
• Any contamination or debris on the sensing elements in the probe of the MAF/IAT sensor
• Any water intrusion in the induction system
• Any vacuum leak downstream of the MAF/IAT sensor
• An intake manifold leak
• A supercharger inlet pressure (SCIP) sensor seal that is missing or damaged
• A manifold absolute pressure (MAP) sensor seal that is missing or damaged
• A stuck supercharger bypass valve--Refer to Boost Control System Diagnosis.
• A skewed or stuck engine coolant temperature (ECT) or IAT sensor--Refer to Temperature Versus Resistance.
• Any type of restriction in the exhaust system--Refer to Restricted Exhaust.
also check to make sure your barometer is reading correctly as well in hpt

Did you put the rtv around the maf housing or gasket? How did you do it? Im worried about getting it on the sensor. I have had nothing but problems since I changed my maf, the car is now undrivable and stuck at work. When I bought it it had an open airbox with no filter and maf was unplugged. I decided to get cia until I can replace stock airbox, I ordered maf and left it unplugged until the maf arrived. I then changed the maf at work and it hasnt ran right since. Tried unplugging it again it still wouldn't run right. It has since rained so I know if its wet it could cause this but it didn't look wet, I tried unplugging battery for 15 mins and haven't found any leaks in intake and like I said it ran fine until I changed maf, i was told maf had to be AC Delco for these cars so i ordered one it will be here tomorrow but now I'm wondering if it's not leaking at housing? Would it cause horrible air fuel issues?
