I don't clean my tires, but I do take the longest way possible through the grounds to staging. I run all season Continental DWS, nothing exciting there either. I have a couple 116 mph time slips from Sunday, but crappy 60' from experimenting with tire pressures and tune changes. Just got to be too many people to make it worth my while beating the dead horse... I will try to sneak out on a week night and do another impromtu track day. lol
New PB but not quite promised land...

I just ran this past Friday. Couldn't break 12.5's outside temp was mid 60's iat2 temp was 155-160 also. That kinda killed it also

Great job though, and I hope that 11.99 becomes reality soon!
Here is a side by side comparison with my personal best. It was 40 degrees outside, and iats didn't go over 127.. that was unleashed tune. I have ajp doing the tune now. I have no mods other than tune and k&n drop in. So I am not expecting 11's but a 12.2-12.3 would be cool.

Yeah, I run 12.2's and 12.3's in those conditions. For whatever reason I am usually finishing my runs in the 130* range, even when very warm. So much has to do with the staging lines. Once it gets too busy, I bail. No sense pounding my car if I have zero shot on beating my PB times.
My iats were in the high 150's low 160's in the lanes, it was kind of pissing me off. I think this tune has more in it with some lower tempsclubsfit said:FoMoCoSHO said:It's frustrating.

You can, best I could squeeze with basically no mods is 12.2's and that was in conditions like you are currently running in. So at 40* with AJP helping, you should be there. Traction becomes issue for me when it is cooler than 60'ish. I have never raced under 50*
The only thing I would worry about in the lower temps is fuel pressure... While the IATs are gonna be lower your fuel pressure is gonna take a hit... Something to keep an eye on...
I have had my fuel pressure drop to 700psi before... Car didn't skip a beat..
But I would hate to be at 700psi and start knocking... That would be very bad.. nothing to help dissipate the heat..

It leans out a little but never past .85 the way we have my tune set up for fueling. And doesn't knock during for whatever reason. I will see if I can dig up a log for you guys. But you can feel it, and its ONLY on WOT and only for a split second after a shift after the boost spike.
Have you looked at your LTFT and STFT ? If you feel it hesitate that could be your fuel trims maxing out, and your AFR may not show that happening. Check your throttle position to see if the car is closing it up...
I have been having a similar problem on my E30 tune. My 2-3 shift the throttle closes and you hear the tial BOV dump and then takes off again. I had my 2-3 shift dropped 200rpm to see if that helps but haven't tried it yet. My logs show rpm max at 6100 to 6300 but I played it back in slow mo and I swear my tach hit 6500 in video. I'll let ya know if that does the trick. We are stumped on it. Side note I pulled a ZL1 Camaro 35-120 gettin on the interstate. Lol. If only he knew I had a load from Home Depot. He wasn't happy. Haha
