I was out with my brother in law in his '06 GTO yesterday. It's modded and pulls like a goddamn freight train. Full throttle sounds like the gates of Hell opened.
I noticed that instead of using that deep double-overdrive (fifth and sixth taller than 1:1) he kept it in fourth most of the time at 55-60 mph, motor turning over 24-2500 RPM. Is that excessive? Causing needless wear? I think no because there's not much load on the motor, I think yes because everything is turning over faster than necessary. I drove his other '06 and it had no problem pulling sixth from 45 mph, that small-block Chevy laughing at me as it built RPM's and speed easily.
In cruise mode I always keep the RPM's in the 1500-2000 RPM range. Am I doing it wrong? Seems like it's lugging a little but picks up speed well enough.
