Chask.... no it's not worth it for $300.. nice, yes, but not worth $300-$350 for what it is...

for $60 shipped i'll sell you my GRID board, and you can have it installed in your own ECU cheap, and have the same thing.... it's a "stage 1" tune as well.... i would say wait to get a enthalpy tune till you get larger injectors, grande turbo, and a Z maf...

just my $.02
