Vroom psst BOOM

Question: when you run rich, do you tend to backfire while accelerating or shifting? My damn datalogger died, i replaced the batteries and my information was gone. I dont have a logger right now cause my software is like 4 hours away :thumbdown id put my stock maf back on but i dont exactly have that either. Before my logger died tho i was picking up 8-9 counts of knock starting at 5100rpm then it shot up to 11 at 6-redline. I adjusted my settings then my batteries went dead. I have maf-t 2.02 and im in fine tuning mode right now w/ 3k leaned out 1 notch, 4k rpm richened 2%, 5500 richened 4% and 6000-redline knob 6%. My redline knob was richened up by 4% from before and my 5500 by 4 from before. Anyone think i could still be running rich? Another thing is i now think my part throttle is runnin a bit lean now because i was cruisin for about 30 minutes at part throttle and when i dropped it in 4th gear my boost gauge shot to 16 like its supposed to but i didnt really accelerate. I stopped my car and my turdblow was glowin like i was beatin on my car for hours. I let it cool down a bit and it ran fine ( not a boost leak). Would excessive heat from a part throttle lean condition effect your acceleration later in the rpm range? Any help would be appreciated.

Okay, strike that thing about not having a logger, i had Greg send me some more software. So i did a pull and started knocking around 5300 and didnt stop....i was like wtf eh? So, i had to reset my ecu and set it to a leaner base setting so i would be able to lean it out less to make it run the same cause i ran out of settings. I set it to base knob 2, idle 2 clicks rich ( cant remember if its letters or #'s) mid- 1 click lean, and wot 4 clicks lean. My idc at 5500 rpm-redline is 90-95% :-/, high fuel trim is 96.8%, mid 98.9%, and low is 112.4%. So i did another pull and STILL for some reason im getting 16 counts of knock at 6k and everywhere between starting around 5300. So i switched to fine tuning mode, and did about 3 more pulls in 3rd, and still i see 6 counts of knock progressively rising from 5300rpm to redline when it fluctuates between 9-14 counts. Idk if its because i got my gas from sheetz and its only 92 but its pissing me off. My idle is set so rich and my lft is so "lean" according to the trim. Im not hitting fuel cut anymore but it still sputters and jerks sometimes. Someone gimmie some advice on what to do. Btw in my profile, i have a fmic, but since the car is new, i havent put it on yet.

just an FYI... it will always read 80* no matter what.

yet again, i did NOT know that...how and why is that??

It is part of the MAFT programming, your air temp will never change.

Just so you know, a glowing red hot turbo/manifold does not hurt performance, it helps to hold heat in there, which aids in spoolup.

well, i know its not the best thing to tune your car w/ fuel pressure if you have stock injectors and such, but im on a tight budget and ya know how that goes :-/. Anyways, i put my automatic fpr on my car and my idc went from 94-96% at 5500rpm in 3rd, to about 81. Also, i think i was overrunning my stock fpr that was on the car, cause before i was getting 16 counts of knock at that high rpm but now my o2 is still the same, but im only seeing 7 counts 5500 and up. Any suggestions on how to fix this problem besides the obvious getting new injectors, afpr, fuel pump, etc. My fuel trims before were 117, 100, 101.2. Now they are 88.7 ( :thumbdown ), 100, and 94.6.
