So just the other day i was on the freeway and a Chrysler 300 hemi pulled up along side of me trying to race. so i did we slowed down to about 35-45 mph i went in to 2nd gear and when we took off i felt a lag/bog. He took the lead somehow my rpms took longer then usual to get up and go?i caught up by the time i got into 3-4 gear and beat him but my car has been having that lag in 2nd gear sense? can it be a sparkplug?sparkplug wire? I'm running all motor with bolt ons and a act x3 tuner i was on my performance tune.any help i would appreciate it thanks you guys
