Wow, it sure will take some getting used to that engine compared to your big thumper -4!

I have experienced a similar learning curve lately, but not as dramatic, going from a 2.4/four that pulled from about 2K-5K to a 2.2/six that is virtually "dead" under 4K but pulls well up over 6K (limiter is set at 7200).

I recall we had a thread about the gearing earlier; I had a hard time fighting the aero and mechanical drag in the stock -4 ZD 5th to get up in the powerband (>5K rpm's). Seems like you're right that even with the X 5th you might be dropping under 5000 on the upshift - below peak power so on the front straight it will be tough to pick up much speed.

Keep us posted how it does on the track!
