I recently got a 04 cobra stock with about 60k miles. I plan on upgrading the fuel system ( injectors, fuel rail, regulator and pump if possible), Ignition system, cold air intake, intercooler, exhaust, port and polish the supercharger and intake, pulley swap with a tune. my questions are what pulley swap should i go with, and what tune. I was told that the diablo sport tune would be the best what do y'all think?

 

Kinda depends on what U want from the engine,.,

 

i would love to get as close to 10 seconds or better with out going to extremes It'll still be a daily driver since my work is less than 5 miles away. I've got a drag car in the works to get me 9 or better.
