to HPT, an injector is an injector...... You tell it how big they are, it tells the computer.

you should get bosch/ford green top 440cc's... good for around 13-15 psi, which is good for around 250 depending on your setup and your tune. Those are the injectors im running and hpt handles em just fine, the computer/hptuners does not care what size injectors, you just need to fill in the variables in the hptuners software so that it can compensate/take away anything it needs to, to make the car run normally with the aftermarket injector size

ok that sounds good . ..... does the hptuners prgram do anything with the o2 sensor? the one off the header? and i know this may sound stupid but is there and pre setups i can download on to the hptuners?

there are file repositories for hpt files.... there is a thread here with a link to one so that you can download them... i checked it out once, there are not many yet as this is new for j-bodies... about a month or 2 old now.

your stock o2 sensor is not good for fine tunning, all it knows is when its at 14.7, above 14.7, and below 14.7 . . . . if you are going to tune and want to know your a/f's then you should get a wideband a.f guage. I have the AEM UEGO Wideband Controller, im sure there are others that are better
