[s-cars] Boost quest

[Richard Tanimura]

Further testing of the MRC chips show the small problems in the quest for
more boost. I can get 1,25 bar but then I get pressure bleed off above that.
It is some small leak in the boost system. Too small to dump a 2224 code,
but big enough to steal 0,1 - 0,2 bar (2 - 3 psi) of pressure off the top
end. The only real indication I get is needle flutter in my boost gauge at
1,25 bar.

I am going to build a simple pressure tester. I think if I am to seriously
tune this car, I will need one.
