I think it might be your gear settings are too high, and the car doesn't have enough power to match it. Try lowering the settings a little.
What I meant by is that I have tried many different tunes on the 2J and I have set first gear so wide that it can hit 276.66 without shifting; however, I can't find any tunes utilizing all three gears that can make me go faster than I can using only 1st.
In "Like the Wind" utilizing drafting I can hit 290 Here is the 2J setup the way I currently have it.
Race: Like the Wind
Car: Chaparral 2J
Avg Speed: 260-265 in 1st gear.
Top Speed: 289 (when I caught the main pack and drafted by them.)
When the Minolta hit 200, I was going 53
Fastest Lap: 127.???
I even smacked the upper turn walls twice flew into the air and maintaing not only velocity but stability as well. Both times I came back down onto the surface at about 230 and did not even wobble as the car took back off.
Settings:
Tires: Superhard(har will prob work)
Turbo:Stage 4
Brakes: 6 f / 6 r (doesn't matter you won't touch them.)
Suspension
Spring rate front 15.6 Rear 11.6

Transmission (this is tricky, set you final gear as high as it will go, then set auto to 25, then set final gear as low as it will go)
First Gear:.762 (full metal jacket)
2nd: doesn't matter
3rd: doesn't matter
final 2.500
Auto 25
It's quite fun passing the minolta at 290 in 1st gear. The car was exceptionally stable on this run. I will fine tune this setup as much as I can.
If you have the 2J you have to try this.
