I recently had a good metering head put on me car and had the fuel setup to be constantly just richer than lambda one so my fueling seems to fine.
the problem seems to appear when giving the full throttle through the gears- i get 5.5k out 1st, 5.5k outta 2nd then 3rd won't pull past 5k
when i say it won't pull its just boggs so i change to 4th and it does the same(bogs) unless i lay off for a bit then it'll pull happily
any ideas or suggestions?
