The difference between the old and new starters is incredible. As Dave said, with the old one it was like the engine was being hand cranked but with the new one it turns over and fires instantly.
Unfortunately, the hose we had trouble with before is still not sealing. Luckily I have a replacement which I will fit this week.
Mapping session is on the 23rd so I will report back with the results.
