Hey guys, & gals!
08 grand prix gxp 5.3 ls4. Tsp chopa
Working on tuning driving and idle. I am having dfco causing a jerk when activating. Is there a way to help this without having to disable dfco? Also having a very light throttle surge at 20-30 miles a hour driving out of my very large neighborhood. Where can I start looking to take care of this. So far ive got my final airflow pretty close, maf is within 2% in fuel trims. Need to work on my ve next. It cranks and idles and drives good except under the 30 mph area. Only a few times running under 50 it will feel like it stalls but comes right back. Any help and ideas would be greatly appreciated!
Ryan
