avoiding turbo conflicts

[Sachelle Babbar <sbabbar@iris.nyit.edu>]

I forgot to also make a post to be fair to others. This is for TAP, Ned
Ritchey, Scott Mockry, as well as others.

Our cars do have fuel and spark maps optimized for what the factory
specifies. Generally speaking, they aren't going to be terribly
aggressive, depending on what car you have and the amount they can
compensate for your driving may be limited (motronic aside). The turbo
ecus do contain the necessary data to run more boost-to the limit of the
pressure transducer. The spark and fuel curves are probably going to be
extensions of the standard pattern and not be any more aggresive. 

My limitations begin at the electronics phase. Ned, Scott, Igor, etc.
their products account for the likeliness of a more aggressive driver and
curves are altered accordingly for regular boost, as well as higher than
normal levels. Their systems are integrated and you are paying for what
you get- chip, their development, and their facilities costs. In addition,
on some you will get a turbo, some hardware, etc. Again, you probably
aren't getting them for no reason. The tuner probably had the hardware in
mind to assist their proms and springs.

How much power from a chip mod on top of the wg spring? Don't know, can't
say. Better left to the guys those things are coming from.

My experience: A very cocky modifier, (not mentioned above) had told me
everything I did was all wrong. This was on the phone and I saw his car in
a magazine and thought he might be humble enough to talk to a fellow
lister. No dice. He immediately referred me to a tuner, ignoring what I
said. he didn't know what my setup was, but felt free to tell me I was
running excessively lean. Very wrong. I was not running lean in the least
bit. EGT temps were high, but safe (due to higher boost). Air fuel meter
showed a slight lean condition, but safe and well within acceptable. Many
turbo cars will lean at boost, anyway and mine what just a hair under.

Basically, I didn't listen to what they said and my efforts have been
proven on the list. I've helped people get more power for real cheap, but
this isn't to say the real modifiers make obsolete products; I guess
they're just different and are tailored for the needs of different people.
