There well supported but a tad basic for street R33(Stinger version) and waste spark etc.You would need the top model to do it right so best to look for a plugin like PFC or Wolf etc. You need Idle speed,VVT,, boost, Aircon request,and closed loop minimum for a nice road car, Stinger uses it outputs for tacho,fuel pump control etc leaving you short on outputs.Ive seen fuel pumps hard wired cause theres no outputs left so if going EMS look for their topend model,and as your saying the price is cheap i think your talking Stinger.The real upside it EMS are fantastic ppl to deal with.
