Thats all fine if you know what you are doing when it
comes to tuning.  In my opinion most people who say
they can cannot, especialy when it comes to high
powered turbo car or even just turbo cars in general.

Nearly every turbo car that blows blows because of
tuning issues.

So Kevin do you tune? I hope you do if you are giving
people advice with engine managment desisons.

Every so called JWT sucks pig rich car I ever trobule
shot including ones with the so called troublesome 4
bar program had their problems caused by issues other
than the ecu, everyone blames the ecu and then people
jump on the band weagon.  Pig rich has been caused in
cars I have fixed by poor quality FPR's, innacuate
gauges, open or leaking BOV's. bad ignitions, bad or
improperly installed MAF's bad plug wires, people not
knowing that their engines were actualy too lean or
just assuming that they were running pig rich from
readfing crap on forums or beliveing inaccurate
dynojet widebands.

If you have a real weideband (innovate is the only one
worth a hoot), access to a dyno, experiance and
brainpower a calum ECU is probably a good deal. 
Realisticaly most people are missing several of the
aformentioned resourses.

At one time JWT was considering offering a user
programable system but did not because of the
potential support nightmare it might generate.

I think they are very few people who can beat JWT's
conservative off the shelf tuning.

If they could they would be many people who would make
more than my 527 whp at only 20 psi classic with an
off the shelf JWT ECU pr my 204 all motors DE also
with an off the shelf JWT ECU.

So Kevin unless you have a great deal of experaince as
a tuner and builder of sucessful cars, maybe you
should not be giving advice for engine managment to an
owner of a turbo car.
