what a fun project car this has become..i have a bunch of parts waiting to go in, but im still in maintenance mode. so i noticed that the car began to lose more and more power each day as i drove it. so i finally made a boost leak tester today and found my problem! the throttle body shaft seals are bad and will need replacing, but i am super lazy at the moment. hopefully theyll get done in time for cmi

i finally fixed the fuel injector o ring leak but still havent had time to do the throttle body shaft seal.
on a good note, the apexi dp and custom catback is on the car, and the dsmlink came last night also. the car feels a lot better now, but i after reading my logs from the dsmlink, i am getting really bad knock around 5k rpm, and my injector duty cycles are 100+%!! ill change out the fuel filter and run some injector cleaner through the car and hopefully that might fix some problems

changed the fuel filter tonight. MY GOD the car runs so much better. injectors arent maxing out at 100% duty cycle anymore and knock is pretty much gone now. im gonna change the injectors this weekend and hopefully see another drop in the duty cycle, and if that happens, tuning will soon begin!.
on a very good side note, my logger told me that i made a maximum of 221 whp and 247 ft/lbs tq. the car is pulling damn hard and the rear end likes to squat under acceleration
