I went to TTFS for a tune, and Frank was able to squeeze out a few more horses, and smooth out that power curve. The effects were immediate. In fact, i'm definitely losing traction at higher speeds in the upper rpm range. The power delivery is also much smoother. I feel like power just builds and builds all the way to the top without hitting any flat spots like before.
Results:
Before: 294.0 HP @ 7600 rpm /// 240.1 TQ @ 4950 rpm
After: 316 HP @ 7850 RPM /// 244.0 TQ @ 5000 rpm
Not too shabby!
