Hi Juan

Are you running those injectors with the original fuel pressure?
What AFR are you getting?

I also have a 3" exhaust with a small rear silencer and a slightly modified first section (got rid of the first catlic converter), a Squadra Chip running aprox. @20 psi.

This is mine black one on the track

All those pictures where taken on the Zandvoort track

Sorry for the topic pollution

Marc
