Yes the injection is stock.. everything is except
for the chip (Lehman) and an RS2 intercooler. Oh,
the BPV is a brand new Bailey valve. I have not yet
pressurized the intake to look for air leaks,
that is next once I get some garage time. All of
the hoses for the ISV, turbo, BPV etc. are new, but
I suppose there could be a leak somewhere. I'm used
to locating vacuum leaks on NA engines using propane,
but I understand pressurizing is a better process?
There are no driveability problems, in fact it runs
just great. Gas mileage is very poor though, and
there is a lot of soot on the exhaust tip.
Thanks for confirming my suspicion that the
aftermarket chip may be deliberately tuned to run
rich. If the pressure testing comes up empty, I
may try to find/ borrow a stock ECU for comparison.
BTW, looked at your web page for the palm-based scan
tool. This would be much easier to use than a
laptop, too bad I didn't know about this one when I
bought the VAG-COM. Nice job.
