Well, we had a 300 TT come into the shop today and they were saying that it had exhaust upgrades and a JWT chip or ecu, can't remember!! haha, anyway, after chilling at my bosses house, I had an encounter with the car. Simply put, I got a bit of a better launch, we had a short race (didn't even finish 3rd gear) and in the end I was ahead by about a car or so and I was slowly pulling away...or at least I think I was!! haah, it's hard to tell while watching the road!! In the end, I was in front the entire way!! haha, so I really don't know how much those jim wolf technology chips help but that 300 was pretty quick and was driven by a buddy from work!!!
