JET's 335Xi

I like these cars. Do you expect mid 12's out of the current tune, and then high 11s with the turbos upgrade? Do these have an ethanol sensor stock, or is that something you need to add? How well does direct injection work with real e85?

I'm generally unfamiliar with direct injection, is that a mechanical or electric pump?

Yeah, hoping for mid to low 12's with just the tune (not bad for $475!) It is a single turbo on the N55 and I think the $2500 option is going to be good for 450whp and will be what I go with. Bigger FMIC is the only other thing I will need along with a low pressure fuel pump.

Direct injection in these is electronic for the feeder pump and 3 stage piston on the high pressure (3000psi). The low pressure pump is the one that runs out first and most people just throw an inline 255 helper pump in there.

I also forgot to mention is has the Valvetronic 3 in it, which has full control of valve lift. The throttle body in the car is only a safety device and is wide open all the time for better fuel efficiency. Intake amounts are controlled by valve lift.
