My L-jet version does not have any sort of manifold pressure sensor. it 
does have an oxygen sensor.

Basically the system runs off excess fuel pressure as boost rises. I figure 
as soon as the turbo kicks in, the flap in the air flow meter slams wide 
open so the injectors are at their maximum duty cycle. Then the fuel 
pressure regulator takes over.

I doubt I could do any better with a programmable fuel injection system at 
the boost I run. The dyno said I was making 123HP at the wheels. I believe 
this car originally made around 80 HP at the wheels.

If I figure in the drivetrain lose, I've went from 102 BHP to around 154 
BHP. And 7# of boost should give me a 50% increase in HP and torque.

Interesting is that the first generation Honda S2000 makes over 220HP but 
just slightly more torque than my Spider. But I don't have to rev it as 
high to make as much power! And for allot less money!
