Sounds better. What rpm's it boosting at now?
Put the pyro in my truck yesterday. Was surprised I could only get it to hit 475 deg C on the fairly short test run up the freeway. That's pre turbo, truck is stock except for bigger intake and brake back exhaust.. Having said that it was a cool night and I could only get it loaded up for a short time, probly like 10 or so sec..
Went for bit of a hill run today. Maxed @ 550, 2400rpm wot, straight drive after about 25s. Interestingly, once the hill levelled out slightly I changed to OD, still wot but 1800 for 30 or so sec, went down to 495 and stayed there.
Thinking, does your truck have a dpf? If so that could explain the big temp difference as the Aus spec ones don't.
