i have the Ecopower 9-5 linear sportwagon, and want to tune 'er up. what can i get from the tuning wizard in the T7Suite? what can i expect to see as side effects? Would it really be worth it? i mean, will i notice a difference? My buddy in his Acura TL is always shoving it in my face about how much faster his is, and i want to even that out some.
