  3. Do I need a tune revision if I put a DW400 pump in

    Does the DW400 single pump need a tune for my 2015 gt, or will the computer be fine with the bigger pump? If I don’t need a tune revision, would it be better to get one to optimize the pumps performance?

  8. Fuel Rails

    Just recently made a switch from 93 to E85 on my boosted 19 s550 GT. Lund tuned the car however they said that it’s cutting fuel up at higher RPM 6800ish to 7500, they are saying that it must be my fuel rails, so my question is which upgraded fuel rails should I go with? I’m running ESS G3...
