I just took the car for another test drive, still doing it, I put the UTEC on map one and took it for a ride, UTEC allowed normal timing again but the ecu was still wanting to run -10 degrees and knock counts on the ecu of about 37 while the UTEC was seeing no knock...

alright, well if your sayin the car feels sluggish, then im sure it cant just be false knock counts.... has to be somethin with either the air or fuel as they combust and make power=car moves... so it seems your air intake volume seems fine and nothin is stoppin it, so has to b somethin with fuel, have you checked injectors,fuel lines, fuel pump....etc. imo, prob to do somethin with fuel delivery...

I haven't checked the fuel pump yet, but injectors and lines seem to be fine, im thinking maybe it could be my maf, has anyone else had this issue with their maf?

If I'm looking at your log correctly, why is your 'loadcalc' showing 30 or 40, but the speed is 0 or 1-2? Also, at idle, your load appears way to high, which would indicate that the engine is doing too much work while sitting still. Has ECU been hit a surge? If you read the ecu and save it, does it compare exactly to your original file that was loaded. You might try reloading the hex file and see how it reacts. I'll continue looking at the log.

yea i am not sure how the ecu could have been effected as the battery had been unplugged for the entire time until I started up the car after the install had finished...

Isnt there actually a knock sensor near the transmission or actually in it. When I was troubleshooting my P0300 issue I came across some info like that.
If the knock sensor is going crazy the ECU doesnt know it's false knock and is still going to try and pull timing and your car is going to feel sluggish.
load 30 at idle is not that abnormal. At idle the ECU fluctuates all around 10, 20, 30 etc. The ECU MAF scaling is not very accurate at low load cells. Hence why people rescale their MAF's to fix fuel trims when they have an intake.
Cleaning my MAF made my fuel trims stay at 100 in Evoscan again. They were wandering to 124.
