Was thinking about calling JWT and asking if they have a little less rich code for the ecu. I know I read about ppl loosing power when switching to 555's because the JWT 555 program runs so damn rich. I remember Seedy talking about Greg's 280 w/tt motor running 20psi due to a different JWT program made for racing. I might call em and ask. But it will be a few months before I can afford to put the injectors in due to other upgrades I want to do at the time. If you get a chance give me a quote on the polished plenum if ya could. Thanks, John
