I dont care about fuel mileage, its not a Daily driver. My car has under 30k on it.

In my situation would you still spend the extra bucks to get the CP with Meth/bungs just in case? The price difference is hardly anything.

Looks like stage 2 or 3 lpfp + hpfp or PI upgrade for E85. PI is Pump injectors, correct?

You probably won't need to upgrade anything in your fuel system unless you want to run a high percentage Ethanol blend (E40-60). The only way to know for sure will be to take some data logs of your low pressure fuel pump (LPFP) and high pressure fuel pump (HPFP) performance. You'd only need port injection if you wanted to run on 100% E85 (no blend). You'll be fine installing a LPFP upgrade to run up to around an E60 blend or otherwise max out the HPFP.


335i Coupe: E85 BB flash, JB4 G5 ISO (map 7), DCI and 60% E85 blend: 11.7 @ 120 mph.

Former Best with JB4 (G4, map 5) DCI and 40% E85 blend: 2009 BMW 335i Coupe: 12.173 @ 109.490 MPH
