I'll let you know how much of a difference it makes here shortly. I'm stepping up from a Turbonetics Cheetah Stg 3 (somewhat similar to a 49/44..I think..lol) to a GT6152. If I had to guess, I would say there would be a noticeable difference in the two, even at the same boost level. Just have to remember the 62 will choke up more than a 44 if you have a stock i/c, downpipe, etc. I'm gonna see how it runs with the stock convertor, but will swap my Pat's 3200 in before too long. I have a feeling traction is about to become a worse issue than it already is...... :biggrin:
