Yeah the KTuner 21 does really drop off at the top. That's why I prefer the TSP stage 1.Yes, it's my own tune after a lot of logging and experimenting.
It's a dyno plot and numbers may vary from dyno to dyno, but compared to my first tune my curves are a lot flatter, I have a little less torque pre 3500 now and a much beefier top-end. My first tune had a 211whp spike at 5400 to fade down to 190whp by 6400 rpm (typical for a tune based on the 21 starter). I have tried countless boost target maps to try and figure a steady torque / power band. The tune can be further refined but there is not much point in going after the last 2-3whp
No, it is a complete custom boost target map, with tuned MAF scale and custom ignition tables
Your power curves look so nice and flat/smooth. Have you considered offering the tune to (non-Si, manual) members here for a premium?
