I hear you. If a single intank could do it 2 inlines build off the same exact pump I have confidence will work too.

Yeah that was an issue with the last ECU. Idle and part throttle decreasing loads were pig rich… it drove like poopy.

I am going to run the VEMS standalone ecu in this car now, cant decide if the extra $300 is worth it for a good base tune from Lugtronic to get going, or just run it out of the box and do it ourselves. Either way the VEMS has a decent (what I heard) self tuning feature to get you in a ball park, then I can play with the tables as we need after.
