GT-R Speed Density

This option is for doing a remote (email) tune on a Nissan GT-R R35 with an intermediate Y-Pipe, down-pipes, upgraded intakes, upgraded fuel inejctors, upgraded fuel pump and upgraded intercooler and a speed density conversation kit.  This is considered "Full Bolt Ons" but with utilized speed density style tuning rather than MAF tuning.  You must already have a Cobb AccessPort.
