Then don't change anything.

@1bar and bit too rich AFR~10,5 on boost

any suggestions what to do to reduce turbo lag?

definitely less fuel, and maybe a bit more ignition advance in "no boost" area

But it's not easy with the standard mikroplex. There you must change the position of the TDC-Sensor and then the injectors maybe "inject" to early.
But you can work with some valves to have "more ignition".

Which pistons are you using?
Is cyl. head stock?

Czesc Lui!

You can "play" with the cam a bit. But maybe you should try a 12.5:1 up to 3000rpm. Engine advance is also good up to 2 degrees max in no boost area.

You'll have to know that your engine (uno-punto turbo) can make up to 400hp and stay at 1400cc. The secret is in the head, the electrics (ecu), turbo, the parts you'll use and ofcourse the man who's going to "build" the whole thing.

There's an example of a Greek Drag uno with 1.400cc and 398hp.



And no, I'm not Polish. But my wife is.

To narazie.

engine interials are stock

I made a mixtur leanere in no boost area, it helped a bit.

Now I have more advanced piggyback computer, I can directly control injectors opening time and retard ignition up to 45deg. I'm trying to make antilag system
