ecu reprogram-xj sv8

I brought the car to jag last week and they checked out the car for the vacuum leak. no leak. the tuner shop was unfamilar with car the the sound they heard was the relief valve on top of the blower. the tuner shop does vw/audi/porshe. the a/f mix got to rich at abouth 3500 rpm and the hp gain stopped at that point. today I had the ecu reflash again and the fuel mixture issues should be solved. the car is much more responsive and feels faster. got it on the highway today and was cruising at 80 mph at just 2000 rpm . acceleration is better.. easier to get to 110 mph also. I am going to trying and get the car dyno-ed on saturday after work. I hope to be at 400 rwhp.. I will post the results. last week got new tires and had rear brakes done also.
