When you start your car, where does your tachometer needle sit. It should be sitting around 750 RPM's. In 5th gear, at 70mph your tach should be reading around a little over 3k RPM's. Also if I remember correctly, in first gear at 15mph, your tach should be reading around 1.5k.

my idle is at aound 800prms yes. but my first gear is doing 15mph at 4500rpms and 70mph is around 3500rpms in fifth gear. i need to get it checked thanks for the help

i have a 95 420a completely stock and in my 5th gear at 3500 or so i hit 100 so your speed sensor is prolly going bad dude

[kristoffpistoff8]

hmm.... theres no way your tranny must have a much bigger gear ratio or sumthing...

if you said around 4k rmps that might have sounded a little btr lol, thanx for the help tho

@kristoffpistoff8 Still lookin for help on this?

[mike10709]

whats your engine light on for?? used a OBD on it yet??

[NIRVANAxOWNS]

in my rs im at 70 mph around 3k

[eclipsegs0]

top speed is like 120 so its prolly fine

[benspilk900]

Im up over 3k going 70, so 5k for 100 isn't that bad. your clutch could be slipping though, you have quite a bit more power than stock you know.

[m00nBALLOONS]

If you wanna know how far off your speedo is, have a friend drive at 60 mph on the freeway and drive alongside then just look at what yours says. then you don't have to replace anything. Just remember how far off your car is and do the math.

[Goetia78]

It looks like the CEL is on. Have you checked the wheel speed sensor?

[PaulRSTEclipse]

Wow... That's a bit off, lol. I'm hitting 80mph 3.7k - 4k ish. My revs stayed the same after I boosted.
