I am looking for a very specific tuning file, at least I think I am. First off, I don't know what kind of equip I actually need to re-flash my ECU. I have a 2001 Jetta MK4 1.9tdi 90 hp ALH with what most call a Stage 3 tune. My boost runs @ 18 psi and I currently have .205 nozzles. I have a 17/56v hybrid on the way (a complete rebuild of my junker turbo) and I have decided on HFLO-X .280 nozzles and a 3-Bar MAP sensor.
I would like a tune that keeps the boost in the 24-25 psi range at WOT except in the middle of the power band I would like 27-28 psi.
I realize I have way more possible boost and fueling available with this equipment, but until I upgrade some more of my hardware I am not interested to what she will really do on the street or the dyno.
I am comfortable with these nozzles working just fine after I have had them balanced and pop tested; .240s are not big enough, and the .260s aren't available anytime soon, henceforth my decision to use .280s. I live at 4600 ft elevation, and seldom ever change more than 200-300 ft difference in elevation, so the 17/56 was my only wise choice for power and reliability.
With the exception of the big nozzles, wouldn't this tune be almost identical to a healthy vnt-17 tune or am I missing something? Is anybody interested in helping me out with this quandary? Thanks in advance.
