Qs bout my maf?

[92Snatch]

Hey guys...my name is Jon...met a guy named Scott and he told me to check the forum out. Im a member on Nloc also. Heres my Q for you guys. I have a 01 Lightning..mods:6lb lower,CAI,idlers,COPS,1 step colder ngk pluds, boost bypass mod,catch can,ported eaton,DSP tuner. I have the 93 pulley tune in it right now and added fuel a lil on top for the ported blower. Im getting a bank1 and 2 lean code bout evry week or so..no check engine light..i scan it with my tuner. I was wondering if this might be maxing my maf out. It has a brand new sensor in it. I want to datalog it, but im not sure how to get the playback and what not. If somebody could chime in and help me out so i can check the voltage at WOT i would greatly appreciate it. I also have a Mafia i can put on it if need be..but need to know what to set it at. Ive read about it could be maf,02s,vac leaks. The only place i havent looked is on the lower intake90...i cant reach it..lol Im getting a buddy with longer -skinnier arms back there. Also on my catch can..i have both valve covers vented to it with a filter on it..now that line on the pass is running to it and i have the upper plenum blocked off...could it be acting as a small vac leak plumbed like that? Any help is much appreciated as i want to enjoy the truck and know its right..Thanks

If your not maxing out your MAF with those mods you will be when the weather cools and you go WOT. If you have a MAFia I would throw it on ASAP. From what I understand most guys set them on 2 but I believe you will need to get a tune for it also.

Yeah..i know ill need a tune for it....just want to datalog it so i can see whats going on. I plan on getting a tune from Amazon. I had it tuned at Delk the first time and had fuel pressure probs at WOT...fixed that....but i think i want to try Amazon..will prob be a mail tune cause i cant drive that far to his shop. I just want to let them know where the truck is so they can compensate for it and get it as close as possible.

I kept getting that code and I took the oil seperator off and it cured the problem.
Datalog maf counts and see how close you get to 1020. The max is right around there.

i would log it but nobody will break it down for me on how to..:shrug:

Im thinking bout redoing the catch can and see if it helps like on your truck. I just might have to route it a diff way..im not running it without one..mu IC was caked in oil..cleaned it up like new.

What hand-held do you have?

It says DSP tuner in his first post so I am guessing that means Diablosport :shrug:
