[urq] EFI + MAC-14 maxing ataround 5k RPM

[Cody Forbes]

Which driver are you running your injectors off of? If you are using the 
bank 2 driver then we are 75% closer. Bank 2 is being driven at double the 
duty cycle of bank 1, which indicates a setting off in the 'constants' menu.

Also you are mega rich any time over atmostpheric pressure. From what I see 
you need to lean it out in the over 100kpa section, aim for between 0.65 and 
0.7v on the O2 as long as it's under 200kpa.
