New Improved Kleemann Software
As stated previously, I could not pass PA emissions inspection after K1 ECU tune about a year ago. Cory told me I needed new Kleemann tune so I had MB send them ECU and Kleemann installed new tune.
I asked if the new tune would hurt performance and was told that Kleemann stated that the new tune would increase boost and improve performance. I was skeptical until I got the car back last night. Performance is noticeably better. Car seems much more free revving. If indeed performance has improved, well worth the aggravation of getting new software to pass inspection.
I only hope I pass inspection since I need to put on miles and take back to MB for emissions test in about a week.
