Can you cause problems with pressure in a A4 94 lt car? My car started having issues at wot after the tune. The guy who tuned the car said it was because my tranny was slipping. I took his word for it and replaced the tranny I am now having issues with the new tranny so this time I took the car to a transmission shop and with in a half of a block he told me that it was a pressure problem. When the guy tuned my car he loaded a tune that he had in his pc to use as a place to start. Well he didn't realize it at the time but he used the tune from a M6 car. I don't know if he changed it or if he added shift points in. Could this be my problem. I called him soon after the tune and he pushed all the blame on the car and tranny it turned into a big ordeal so I can not go back to him. I am also having a problem with the car running hot and I have tried everything from water wetter to hypertech thermostat and even a new cap. Water pump was new with the motor build.
