Boost 'struggle'??

pwpanas · 09-02-2011, 01:34 AM

There's more load on the engine in higher gears, which means you're asking the turbos to work harder. 105K km is very low for a '93...are you sure that's the correct mileage on the engine and especially the turbos?

Also, maybe a dumb question but by any chance does the rpm needle go up without speed increasing?

If you could post a youtube vid with sound, that would be great. Hopefully it doesn't sound like this:
