Which ECU mod, 91 200q

[ekellock@juno.com (Edward J Kellock)]

I was all ready to call Ned and schedule the work (IA Stage 3).  Then I
spoke to Anderson Brothers of MN who said they prefer Hoppen.  They said
Hoppen imports the Audi Motorsports mod (??) and it can be had cheaper. 
They said Ned's goes for more boost (and $$) but has to use more retard. 
I guess I don't understand the problem with this as long as the engine is
still protected.

This will be the only power mod I'll do and I would like to understand
the difference between these two different products.  I am happy with the
basic nature of the power and don't want to change that, I just want...
MORE POWER.

TIA
