While we're discussing tuning, is it possible to have a "performance" tune that's still safe for nitrous? Or would that type of tune start leaning out the car?

Also, I have the ProFlow MAF; can this stay, or is this going to make tuning the car more difficult?

One last one; I have an SCT XCAL2; can anyone recommend a web-based tuner (a la Brenspeed, ADC, or wait, no, I got it...... Hypnotic Illusions, right?!)?

Thanks guys!

Edit: The full NGK part number is 739-TR6, correct?
