Morning all.

Alan. Re-map occurred prior to customer purchasing vehicle. No problems with driveability until he put a K & N filter on and gave it a good thrashing - then problems started. K & N Filter now binned. Martin. Yes, I took a sharp intake of breath when I saw the Fuel Parts MAF and customer is aware of the ramifications. Spoke again to the customer this am. and apart from the stalling, the "lack of power" manifests itself as "shuddering when the turbo kicks in". If I have to go back to it, will do the koeo check and will also check inlet vacuum.

Regards
