The title tells it all.
The car has a KLZE with KF transmission.
Acceleration is nice, nothing to complain about.
But Top speed is way too low:
Running 205km/h @7200 rpm, 225km/h @ 6500 rpm. (I was able to reach same speeds with my old K8 setup)
![Sad :(](./images/smilies/icon_sad.gif)
It reaches these speeds without problems, but then it seems as it would not have enough power to continue.
Even if I would continue 10 km with full throttle, it is unable to get higher rpms.
In third gear, I can easily hit the limiter @ 7500rpm.
I don't think that the KF transmission is too long, because if so, I would expect it to reach higher spped in 4th gear than in 5th gear.
Exhaust system is: XS Headers, matal cat, and 2.5" free flow exhaust System.
The change from stock exhaust system to the new one made no difference in topspeed, acceleration was imnproved.
Distributer is new.
Tried with KL31 and KL36 ECU, tried different spark plug leads, tried new air flow meter, tried fuel pressure regulator, nothing made a difference.
Any ideas what could solve my problem?
