Hi there I'm new to the s3 8l, I've bought an immaculate 81k full audi history s3 and owned it for roughly 6 months, every time I've used it it's been fantastic, the battery weren't all that great so I've had it changed, and ever since that day its had boost issues on its first run of the day, so basically I could start it up tomorrow and take it out do the usual and get it up to temp, then give it a foot full in say second gear and theres hardly anything other N/A power, now if I pull over switch the car off then turn it back on and pull away it will then kick you up the **** and give you full boost, and then be ok for the rest of the day, park it up get back in it the next day and go through the same issues again, has anyone had this issue and guide me in the right direction, I believe its had a stage 1 map before but unsure what map it is, maybe the battery change has confused the ECU and the map?
