What do I need to look for when deciding on a TT kit?
What kind of HP and Torque numbers are you wanting? If you plan pn going past 350 rwhp, then you will need to address timing and fuel. Be cognicent of this when purchasing your kit. For instance, the Greddy kit is safe up to 350 RWHP, after that you need to upgrade your fuel and put in a timing solution. Where as the PE kit addresses both fuel and timing (with the optional Technosquare Re-Flash).
The point is, decide on what you want and then look at which kit provides your solution.
