I installed a chip in the engine control unit that also provides a significant boost in power. Now, I'm having a problem where the 5th gear feels a bit short, and the top speed is not ideal!
How can I only extend the last gear, and most importantly, with what?
We checked yesterday.
The large sprocket is the same one that comes from the 90 horsepower Golf 3 TDI with the GKB ASD transmission (if I remember correctly).
'I also have the gearbox installed. Mine reaches around 4500-4550 RPM at a speedometer reading of approximately 220 km/h.'
It's not that much longer. The TDI engine also starts to lose power around 210 km/h. Are there any other alternatives besides a 6-speed gearbox?
Is that a long size 5 from the accessories?
