[Tireiron]

I started with Gamma which had everything I thought I would need at the time. Since then I have unlocked the external wideband feature because I am using a Zeitronix for all of my gauges because of the single display unit (no clutter of gauges in the beautiful factory SVX interior). So far everything else with the Gamma is plenty, although if I went with the Epsilon I could play with traction control later once everything is tuned up, although spinning all 4 tires in first gear without traction control can certainly be fun. But as far as running the car, the Gamma has everything needed aside from my choice to use the external wideband. If you want the autotune feature I would suggest going with the Hydra internal wideband and their wideband kit. So far even with help from Hydra I have not been able to get the external wideband autotune to work.

So you know I have a 6MT and a cammed, forged, supercharged engine...
