I just recently found a Z TT for 15,000 and am planning on buying it and my first upgrade was gonna be a jet chip, until I heard about super chips. From Super Chips Inc., they said that it would increase 70bhp and that the engine had much more potential and could be put up to over 400hp with just the chip upgrade. I was just wondering if anybody has gotten the super chip upgrade and wonderign if it would be a good buy at around $250. Thank you.
