Subject: [s-cars] Boost quest

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.








Hmmmm... I too get occasional needle flutter @ WOT, @ or near 20-23 psi.
Car drives fabulously though.  Thought that was wastegate, no?
