more likely that the MAF is just seeing more air than its comfortable with and is cutting fuel.
What have you done to your MSP today?

Its not dependant on engine temps.. does it in the morning if the car is cold or warm doesnt matter on car temps.. only temps outside.... its so bad that it at times make the seat bets lock and try to give you whiplash even at 6psi at moderate throttle... not even trying to dog it out.

thats why I'm suspecting that its just the maf seeing more air than the safety protection will allow.

The messed up part is their is another msp in my area same color more mods and his doenst do it in the mornings. so the temps are the same so it had me puzzled.

just tune it out, mine use to do that all of the time, I actually use to hate driving my car once it got cold out, and most of the time I just wouldn't go into boost when it was cold, even sometimes when the temp. dropped at night it would fuel cut like crazy if it dropped enough, even with the MAF sensor relocated, but my mud guard things going to the cai has a little vent in it, so it sees cooler air than most peoples that have the full coverage of the mud guards, but unless you don't have something to tune the fuel cut out, your SOL..
oh, and also I went outside to check my brother's car, see if the battery did it, no such luck, so once I get a car home so I can go out and get an OBD scanner, I'll see what that damn CEL is, I just really hope it's nothing big, and I don't think there should be any reason for it to be that way, I didn't really change anything anyways

Hm... sounds like im SOL then.. but its werid that my buddies MSp doesnt do the same thing... same weather and both cars are on the stock tune... no piggy back or standalone.

do you both have cai? if he has a sri and you a cai, that would explain it, or if your mud guards are cut or something like that to let in cooler air, that would also do it

I have a SRI and so does he. I have my fender liner in and I assume he does as well so.. no telling
Edit: only major different is he has a full exhaust, upgraded smic... and i have a Perrin FMIC, and only cat back exhaust

ya, the fmic is probably able to cool it enough to make the difference, is your maf on the cold pipe?, but ya either way it is probably the fmic cooling the air enough to make that difference, the ssafc is great, should be your next buy
I noticed the same thing last weekend when I was autocrossing. It was in the low 40's in the morning and my car was cutting fuel like crazy. It was really pissing me off because I know my time suffered a little. Hopefully soon I will have some money saved up for a SSAFC. Seems like everyone praises them for our cars.

nope, my MAF is in the stock location on th intake right after the filter

hmm, well it must really only be a small temp. difference that is causing it, but you should look into relocating the MAF, that usually helps a little, especially once you get a ssafc

my personal experience is that these cars run VERY poorly on a FMIC without relocating the MAF. My major issue was stalling, even with a recirculating valve, I relocated it before it got cold though, so I have no idea if that would have been an issue or not.
I would really honestly just attribute the difference to either how the car is breathing, or the fact that they're finicky. Take your pick! lol

well, I went to autozone got a code reader, came up with P0102, and P0505, was searching around for what it was, and saw that someone had the same issues and later found out it was just an uplugged sensor, so after looking around, I did a double check and found out that the wire that is right on the throttle body, which I am guessing is the idle control system, or part of it at least, was unplugged, turned it over, and the car idled great, drove it up the road real quick and everything was good, except for the damn fuel rail leak still,
so tomorrow I'm just going to take out the 2 injectors that are close to where the leak is and the bracket is to make sure those O-rings are good and didn't get damaged, and if it isn't the O-rings, then I'm not really too sure what I am going to do yet.. big PITA, wish there were more/any aftermarket fuel rails available, I even have a stock one but I can't connect the stock one to the fuel lines that are run in the car now, and I don't want to have to replace it all right now

Well i bummed a friend and his scanner and my MAF voltage goes all the way upto 23 when it cuts... The range is anywhere from 0.5-23 on a single gear pull.... And AFRs are 10 flat!

Oh forgot to mention its been confirmed.. the car is hell of a lot faster then it feels! I was able to keep up with a cobra when checking out my MAF voltage on my car

lol, ya it's funny, I like to pass people on the slow double dotted line on highways going up hills that trucks are suppose to use when there is a lot of traffic, I can pass a large amount of people usually while going up the hill, and gain some speed pretty quickly, it doesn't feel very fast, but it's funny because the dodge stratus I have or my moms mini van I was driving a little while ago had trouble keeping speed going up the hill unless I gassed it hard, making the engine sound like it would blow up haha, you get use to the speed/peppyness of the car pretty quickly when driving, you tense up and expect it, makes it seem a lot slower.
but ya as far as the MAF and fuel cutting, usually once my wideband gets down to 10.0, it's only a matter of a few sec before the fuel cut hits, I am pretty sure that it is really lower than 10 afr, but obviously the wb only goes to 10
