To be honest, they suck. The standalone was the way to go. Since Paul doesn't make them anymore, you would be better off with a xic controller next. You would need to call Neil McLaren about those. My guess is he stopped those too. In that case, I would call the ecu company in Canada that made them. That company makes standalones for airplanes and cars. Their logo is different but the box is the same. I have talked with the owner there about the xic controller. He helpedme understand the controllers limitations. The xic can only control fuel for boost add to a stock displacement and factory head, no porting. If it has a ported head, then your only option is a sstandalone. Lastly, if your engine has a factory setup (plus a forged rotating assembly or a headshim), then you can try to use the others. Derek at attitude industries in Utah sells the dobeck box. He is very knowledgeable about them. If that is the route you go, then you will always be making minor changes to the controller every time you go ride. That is because, those controllers do not accommodate changes in barometric pressure or changes in humidity in the air that happen naturally over the season. That said, if you're reasonable with the boost...10 to 15 psi on a shimmed or low compression engine, then you maybe able to get away with it and enjoy the sled. The problem arises when you start running the sled closer to the edge. If it runs a hair lean and you don't notice, you can detonate the engine and ruin it all together. The more boost you run, the more sensitive the engine is to detonation and catastrophic failure. I hope that helps you. If it was me, I would call Paul Horschel, the xic controller manufacturer, or Derek at attitude to discuss things with them. Good luck.
