Can a 99 sport speedo give dodgy readings because sometimes when I'm on the dualcarriageway the clock says 70 but it feels like I'm doing 50! same when I'm doing 30.
Any suggestions?
I realize it's probably me

they are not 100% accurate and i think are usually a few mph out (5-7mph) correct me if im wrong anyone. U would need to get ur speed from a GPS or sat nav or something to be more accurate

I've heard this but it's as though that the engine is struggling too come to think of it

Lol, whats with the repeated bumps?
You speedo wont be 20mph out at 70.
What revs is the engine at, and which gear at 70?

Double the revs in fifth. i.e. 3,000 RPM = 60 MPH (roughly)

at 70 the tachometer is showing between 3-4000 RPM, closer to 4 really.
Also my engine doesn't feel right sometimes when accelerating up a sliproad (yes up!). yet other times it's completely fine. I feel as though it's struggling after 65-70 ish.
Any ideas?

My speedo is shockingly out. I go through 50 cameras at 70mph on speedo. GPS reads 50mph.
Had 140 on clocks, was only doing 117
