An update:
I am finally booked in for a custom/dyno ECU map for this Friday @ a local tuning shop. I decided to bite the bullet and try this out. I will also raise the rev limiter to MTH level, i.e. 7300ish...and if the shop is able to do exhaust work, I will try to get the flat section of the
JCW exhaust (

Last time when my car was dynoed I got very similar somewhat disappointing results as Aberdeen Al documented here

Let's see how this goes. Will post some before/after results once I get the car back ...
