Newbie needs sage advice

[Bruce Plecan]

None sage response:
To really make a difference at the level your at is gonna take some money.
The Felpro SEFI, Wide Band O2, ecm sounds about what you'd like/need.
I have 0 personal experience with it, but have heard nothing but good about
it.
This is from 3-4 people at the gn list who are running it.
Any time you run out of calibration room, your out of ecm, IMHO.
Pasting/bandaiding things is a waste of $$, and effort.

| I am fairly new to the list so forgive my relative lack of knowledge.  I
need
| your help with a fundamental and somewhat philosophical question:     Is
it
| really worth replacing my stock FI system with a quality aftermarket
system?
| The car is an 86 Porsche 944 turbo with early Bosch Motronic converted
from vane
| to hot wire.  The computer incorporates a manifold pressure sensor, which
I
| assume references boost level and adjusts timing and fuel accordingly. (I
don?t
| know the range of this sensor however, as I am running far more boost than
the
| factory intended).  The computer is crank triggered.  In other words, it
is my
| impression that I already have a lot of the features that make the
aftermarket
| EFI systems desirable.  So far I?ve just been using the white-lies method
to get
| the stock computer to meet the added fuel requirement of the larger turbo,
| headwork, cam, nitrous, etc. Other than a minor drivability problem, this
method
| has worked well. However, if there is horsepower to be gained, I am
willing to
| move to the next level.  Is there really a fundamental improvement to be
had by
| moving to an aftermarket system?  Of course, the downsides are clear,
cost,
