Update.....
been fiddling about and my hands are smelly.
RS3 in-tank fuel pump fitted today, with me helping/hindering Steve Jr. Need to do some VCDS logging, but all appears good in the hood and the car runs as sweet as a sewing M/C. So wound up the car, and did some more runs.
12.4 - 1\4 mile run...........uphill!
flat run revealed this...............
(Mainly due to a top 3.4 launch to 60mph) 11.9 quarter @115mph
