I just bought a Mk2 GTI with an ABF 2.0L 16v engine swap. I was told that its running a digifant 3 injection system. i feel that the engine response is a bit delayed. Im not sure if this is normal but it doesnt feel like its normal at all. Theres is at least a 2 second delay in throttle response and im not sure what is the problem.

It would be great if anyone can help me identify the problem for the delay in throttle response. The engine seems to cut out a lot because of this problem. Thanks
