well i finally got me a few runs after my Stall install the first one was a 06ish dodge cummins. i was getting in the turning lane to head home when i noticed some black smoke commming from the cars in front of me. i had to cars in front of me and got lucky they both turned i sped up alittle to catch up to him and ofcorse as i got to his tail pipe he threw a puff my way. i got up next too him and looked over he was looking at me and gestured to let em run. well we both got on it at about 40. sucked because i bairly missed the down shift but to my surprise started to pull. i got towards the top of the gear and was about 2 trucks ahead. the cool thing about it is i was still pulling hard and when i looked back u couldnt see crap but head lights and smoke haha.
the second was a lightning mods unknown, but it sounded mean deff had exhaust. i was stopped at a light and about the time he was all the way slowed down it changed he rolled alittle and i sped up to catch him i got to the back of his cab and he mashed it " about 15-20 mph" i just rolled into it and by about 50 or so i was even and pulled about a truck or so by 70 and shut er down. so far im pretty happy with the results
