Just a little update. When we started getting heavily into tuning, found that the duty cycle on the injectors was maxing out early, with possible leaking as well. This necessitated further learning on my part on duty cylces, high vs low impedance injectors aided of course by everyone here.

Fuel injector guru's - Relation of flow to duty cycle/impedance/ boost

Thanks esp to GJF, DonE and Goran. We replaced the old 55lb low impedance injector with Accel 62 lb high impedance injectors and the car was like night and day. The TEC-Gt system has delivered with great flexibility, allowing us to iron out the idle and cold start despite higher flow. Has taken a lot of data logging and trial and error, but has been a fascinating learing curve for me and my tuning guy.

Final numbers as of tonight at 1.0 bar: 475bhp and 413lb/ft.

Gonna have fun with her for a while, then may take things to the next stage with cam sensor and high flow, low impedance injectors. It is a slippery slope indeed, but a fun one. Thanks guys
