Default At what RPM do these engines usually start to lug?

I think I've finally fixed my misfire problems, or at least significantly improved them. Before installing a new ECU my car was lugging/misfiring at anything under 2,000 rpm in 5th gear and sometimes a little above. Now the engine only starts to slightly lug at 1,300 rpm in 5th gear. Does this sound about right? For those with 5-speeds, at what rpm in 5th does your engine start to lug?

I don't really pull the motors much under 1800

1300 in 5th gear is a good way to spin a bearing

I don't lug it like that when I drive normally. I was testing to see if my misfiring was gone at low RPM and wanted to make sure my engine is healthy. Lugging a turbo engine regularly is definitely a horrible idea.

Turbos love rpm.....lugging at low rpm could be caused from a lot of things

Gas age and octane,
Plugs wires age
Temp, exhaust sensors
TPS
Clogged cat
Faulty air sensor
Low amp battery faulty alternator
Poor wire high resistance
Low compression

1300 is pretty low of an RPM to meaningfully accelerate. My 98 wont shudder in a higher gear until about then so it sounds right. Try and keep it above 1600, though. Probably 5-10 more PSI of oil pressure; a lot more easy on everything.
