Hi,
Bought my Leon MK1 1.8T (APP) last week and needs a bit of work. Car wouldnt run with MAF connected it idled then died and when it did run it was jerky but ran 'ok' unplugged. Did a scan and had some errors, including MAF, replaced MAF with second hand one and cleared the codes. Car is running with replacement MAF but it seems to be slow accelerating and especially in 5th and 6th gear at 4k rpm and about it seems to hesitate and take an age to go up. MPG seems really low, I know these aren't great but it can use £6 of fuel in under 10 miles if I put my foot down.
Also I don't feel or hear the turbo like I did in my golf gttdi so thinking something might be wrong.

What measuring blocks should I be looking at (I believe 115 for boost request and actual boost?) to check turbo health and fuel usage? plus any other blocks that would be good to lock for general health checking.
