Trouble with using tunes found on here.

I am having trouble using tunes found on here. I have the fully adjustable trans and I set max speed as low as it will go and the final gearing to whats recommended. I find when i go to adjust the individual gearing on the transmission it wont go low enough. What am I doing wrong?

 

You're doing nothing. There's a final drive glitch which resets it after you change it and go on track.

More here.

 

I am not able to change it at all. I know about the glitch your talking about

 

That's what happens with the glitch. Messes up almost every tuned trans.

 

make sure you do all the power mods needed, then do the gearbox last.

 

For during this bug I suggest trans settings that do not adjust the final gear.

 

This is the right way to do it.

 

some 15th ann tunes are a bit different on non 15th ann models...

 

Power and weight are slightly different.
