went down to do a little test and tune.. A LOT of junk there.. i mean A LOT! saw a ricer race for money the car that WON went 16.xx with the flashers on! we took my buddy lukes twin turbo 06 cummins down but we had some issues of it blowing through the converter so bad it wouldnt lock up.. or shift.. it would go off the rev limiter into 4th and wouldnt go in until u let off and it would slow down to like 70mph... diesels need lock up to use the torque to really get down the track. also had issues with the engine torqueing so bad it made the bottom turbo hit the frame and push up on the top turbo and allowing a boost leak at one of the couplings.. so it would only make 65lbs of boost instead of 85 where its gatted where it usually hits. it went best of 1.66 60ft (4x4) and 7.53 at 99mph 1/8mi only worked out to 13.6 in the 1/4 letting off just after the 660 to let it shift then stuck it again. still went through the 1/4 at 117 when figured out it should be high 10 sec or low low 11sec 7400lb truck
