I was thinking about buying the accel dfi thruster kit, my car is just way to hard to tune with the stock ecm on my setup(sig is my setup). Also i like the idea i can tune in it many different ways. Should i get the setup with wide band, is it worth it or am i ok without wideband? Should i be looking at this model dfi kit or any other kits? I saw jegs sell the kit without wideband for $999.99 is that everything i need? Is it worth it? Sorry i dont know much about tuning..

 

Thruster looks like a nice setup and if you buy it get the WBO2!

About tuning the stock ECM shouldnt be too hard with your engine, but you should consider swapping to $58 or $59 code to control fuel and spark under boost.
