[4g63awdtalon]

here's the problem-

so i go to set my boost tonight about 75 degrees and as i am going i go from 2k rpms to 5k and at 5k it starts to studder.

so i pull out my logger and did a 3.5 to 5 pull. it gets no knock until 4500 and it goes to 17 knock and 21 degrees timing at 10 psi on a tdo5 20g. if any one could help figure this out for me i would appreciate it i am clueless to it. i checked all vacuum lines and my fuel trims at at high 86 mid 108 and low 100 on a 1g. i have 650 injectors along with 2g maf. i ran the car last night and it had no studder.

thanks

If you could write down the whole log and tell me the trims in percentage then I can tell you why. I would have to say either too much or too little fuel...but not sure yet.
