The other thing that makes a sig difference is the conditions ,I.e, temp , barometric pressure and of course altitude relative to sea level . I just switched to 3.81 gears from 4.10's so I can probably do 100-200 the 3-4 shift too , but will need to go to fifth still for 60-130 mph . 4-5 on this car is not quick lol.

Nice, got it!
For our power levels 3.91 is ideal, you can push the car up to the 300km/hr!!!! do you prefer it from 4.10?
3-4 can be really quick, 4-5 is a bit tricky and will add another 0.3-0.5sec to your 60-130readings.... How many miles 4th gear goes? According to my speedometer is reaching 210km/hr at 8160rpm.
Another reading that we did today and I forgot to mention is the intake temperature. With a weather temperature of 19C the car intake was running at 27C and that when being pushed. It seems that the intake is very well designed and not being affected a lot by the engine temperature.....
