I have been replacing/updating parts on my all beetle in preparation for my Malone tune 1.5 I put in a new MAF, new N75 but had to change the electrical connection, the vacuum check valve, got new bosio 520 .205 injectors nozzles new turbo. Under acceleration there seems to be a hesitation occationally and I wonder if I need to update the ecu settings since I made so many changes b4 the tune or after, I also want to have a b4 n after dyno snapshot printout of the tune results
I would like some feedback as to why it doesn't feel seemless when I put my food to the floor will the tune cure this or do u think it is something else more sinister!
Thanks in advance
