No, it alters only the 5th gear - it drops you about another 400rpm vs standard 5th gear at 70mph or something like that.
Your TDi should easily burble at 30mph in 4th. Mine will burble at 35mph in 5th with the longer 5th gear. What you won't be able to do is accelerate smoothly at low speeds in higher gears. You should be able to cruise in the higher gear and changing down when you need to accelerate.
Interesting, perhaps I just need to adjust to the feeling that the engine is struggling in 4th at 30pmh then, so should that return slightly better econimy than dropping to 3rd at that speed on average? I always worry about damaging the engine trying to make it struggle in a higher gear than it feels it's asking for.
Not sure if the 5th gear mod will really be worth it for me then as motorway driving generally accounts for probably less than 10% of my driving at best, so probably my average speed is between 30-60mph.
