Ok been working on this tune for a while now and im wanting some advice on what I need to improve on. Just installed long tubes on truck with
single 3'' exhaust system and I feel I lost power over the stock setup. truck seems to have cruise control effect when going around 30mph. I have done my
base airflow table many times and it says my STIT are very close. tried messing with cracker and follower tables also. truck is a 03 SS Silverado lq9 tvs2300
