Last time I tried my 2010 XFR at the track it was bone stock except for the Mina axle back. I ran 12.55@111.98 with a 1.82 60ft. I met someone at my local track last year racing his XFR and his car was pulling much better than mine. Well he has now become one of my Facebook buddies and he had convinced me to get a tune and pulley swap from eurocharged. Well to make a long story short, I am really satisfied. Went to the track yesterday and my car ran a best ET of 12.04@116.79 with a 1.81 60ft time on regular radials that are worn out. The run with my best mph of the day was a 12.21@117.54 with a 1.95 60ft time. My best run was done with the weather warming up, if I could have pulled that 1.81 in the morning with the cooler air, the car would have touched a 11.9s. Might put a set of nitto drag radials at the end of the season with cooler air , to get the car to run consistent high 11s. Anyways, all this to say that I was very satisfied of the purchase I have made with the eurocharged tune and pulley.

 

Nice to have some data with a like for like before-after comparison. Helps to show the true benefit of the tune
