Had car getting tuned yesterday and as soon we went wot the a/f would hit 14.0-15.3. We added 20,30,40 percent more fuel and it would get leaner. Car idles fine and doesn't miss . Has twin 340 pumps with 80# injectors . Return set up with -8 feed line. Pump duty cycle is fine. So my question is has anyone got a bad blend of e85. That's all I can think it could be as we had 70 psi at fuel rail when we go wot. So the fuel is there. It like its not burning. Was at 21# of boost
