Just got my dyno done this morning and this afternoon my GMS 85mm MAF arrived.

Now my question is this I am pretty sure it leaned it out a little more up top, The noise that I've been hearing that I thought was my tranny is now I'm thinking actually a little pinging in High RPMS, happens from about 5k+ just before shift, used to hear 3-4 little clicking sounds, sounds like someone has a bag of marbles in the car making noise right? well now with the GMS it's like 7-8 but only under WOT

I know this can be bad but is it bad enough? I only need to get by until I do heads and cam in a few weeks and then i'll have it tuned. should I buy a MAFT anyways? or should I take off my S2 TB and the GMS until I get it tuned. I put 2 and 2 together and just today realized the sound started shortly after my S2 was installed.

Thanks in advance.

Did I read that right? Your a/f looked as though it was above 14 the entire time with it starting out at 16?

If so, that is pretty dern lean. Driving around at part-throttle isn't going to hurt you.... unless you are setting and SES light for lean. Are you setting any SES codes?
I would just avoid the WOT until you get a fix for your lean condition.

No SES light yet. Would WOT cause permanent damage? I know over time it could but I ask because I've had a couple of WOT instances 3 as a matter of fact to test my theory.

But that's only today after I installed the GMS, I've been driving around a couple of months with it like this.

I guess when Heads and Cam go in I should throw in a new set of spark plugs.

I just thought of something this morning, about 4 weeks after I got my S2 I did throw a code. I don't remember what number it was but I remember it was listed as "Bank 2 Switched Lean" I remember thinking to myself wtf? Bad Gas? I cleared the code and have not seen it since.

If I pull the neg for 5 mins it'll force a re-learn right? Should I do this? Also I should add that since a week after my S2 was installed every morning when I start up the vehicle it surges for about a minute till it idles right, but when it's surging it just bounces between 500-900 rpm, and sometimes gets as high as 1100.

Anyone have any suggestions?

Reset my Computer this morning and car died once at a stop sign during the initial drive around. Then about an hour later threw a code P0140 -- System too Lean Bank 1, I remember now the code I threw before was P0144 -- System Switched lean Bank 2.

I'd put your stock MAF back in with the screened ends. That should bring you down to at least 13.0:1 or so....

Ataped my car and I had about 5 codes about the system being lean, 1 code referring to O2 sensor 1 bank 1 switching wrong, and also had a misfire code. Drove around with atap on and NOTHING was wrong, car was even running a little rich, cleared the code drove around for about 30 miles and nothing came back up.

Only things I can think is maybe the during the day today with the hot air it was making pinging happen? IAT temp was 88F

I know It's about time to change my TR55's they have around 13k on them. Are there any drawbacks to using the TR6's on a N/A car?

I had no KR at WOT and O2's were running like .930/.935

Anyone have any ideas?
