Evening all,
Few questions, looking for anybody with experience of the issues below on a CHFC Leon TDI FR 140
Recently had the Leon mapped to approx 190hp at 76,000 miles.
Since mapping the car loses a bit of power at approx 4200 rpm - most noticeable in 3rd and 4th.
Ive logged the air flow through the engine at it maxes at 15.8lbs/min which if im calculating correctly is 158hp?
I dont suspect the map is an issue as I have had 3 cars done by the lad and the other 2 have been spot on.
As I dont have a VCDS cable, whats the cheapest source of one to enable me to do full logging?
What do people think, taking into account the above symptom, is it a turbo issue or a MAF
Thanks for any input..
