Does anybody know what the A/F ratio this chip is set to run on load? (up to 1,3bar boost)
Mine is running 13-13,2 all the way up to 1,3bar,..only did one drag i 4th gear. So no im not using it before i know more/got a decent setup,..Crappy chip?

New parts on the car; fuel pump, fuel filter, regulator, air filter, injectors(803), intercooler, spark plugs, all engine sensors,...Fuel pressure is 3,5 bar without vacuum,.

Thanks

I would suggest it needs setting up properly (or custom mapping), just fitting an off-the-shelf chip often doesn't lead to perfect results.

That is way too lean(on boost) for decent power, and more importantly engine protection, nearer 12/11.5 is better, though some put theirs to 10.5, which is just studpidly rich.
My idle afr is (warm) 15.8, but goes leaner than this on light cruise.
