As you wrote:
How many people out there are running Charlie spring mods or
some other ECU hack, Shrapnel Knobbin or pressure bleeder valve? 
Send me an email directly. Orin and/or myself may want to provide 
some low cost ECU mod for the people out there running with these 
type of mods but who would never spend the $$ to go with the IA solution.
I don't want really want to compete with Ned at IA because I think 
he provides a good mod and a LOT of good customer service for his price.
But......I  kind of hate to see people run these hacks when there is a much
better way to go. Maybe I can start an "ECU club for Men"

I,ve expecting shortly my Schrappnel   knobben(R) from Paul, but before it's 
installed I'm wondering what areas of concern your ECU"fix would address.  I 
think the knob kit readjusts the setpoint for the fuel cutoff (via resistor) 
then simply supplys boost diectly to the top of the wastegate manifold at a 
constant pressure controlled by a PRV instead of a cycling Solenoid valve.  
(have I got this right Paul?) The remaining area would be either the boost 
setpoint, using the SV or the fuel/timimg map area...? Im not an expert in the 
area simply an enthusiast P Eng (Mechanical) Energy/process /HVAC areas.
You are correct that $$ (IA) was the primary factor in my decision, plus the 
list comments on TAP.  However the ability to adjust the peak boost was also a 
big factor... thinking of a valet mode(1-1.2 bar), sporting mode1.9 bar), 
trailering mode(a little less depending on engine temperature etc)..

Sincerly,
