Next steps..

With Dunc's help from Hypertech www.hypertech-scotland.co.uk

1.inspect the pistons/bores with an endoscope through the plug holes - don't need to take head off (also worth compression testing as you say).

2. Drain c'cooler system and remove mechanical pump - check liquid for sludge

3. Purchase electric c'cooler pump and blank off where mechanical pump used to be

4. Remove ecu and replace chip and memcal with spare Sport 300 chip (1.25 bar) from John Hazzard

5. Replace throttle position sensor (TPS)

6. Set throttle position to 100% on Freescan

7. Switch primary injectors if neccessary

8. Refill c'cooler system

9. Move inlet temp sensor from outside of c'cooler to inlet

10. Set up car on Falkland rollers - check knock through Freescan and check a/f through wide band lambda.

11. Replace boost solenoid valve and check connections

12. Cross all fingers

Alternative is to retain chip and sensor, sort c'cooler and boost solenoid etc and recheck knock and a/f on rollers before replacing chip
