Thank you for writing a detailed explanation of what can and cant happen when the fpr vacuum hose can be left of..

Steve posted on here personally and said he realised the hose hadnt been put back on when he arrived home!!

This was a fair journey and imo 100% to be the blame for his engine damage..

I havnt got the lap top infront of me to go over the ignition table again but i can tell you the values are lower than the ones youve just given and the boost versus rpm are true that i have given..


cheers danny
