that's what I said Mark, keep it from Wed morning until Friday arvo if you need to, just make sure it works properly. It sits on an even 14 to 14.5psi until it starts dropping off around 5000rpm, heres the chart

Who said anything about Footscray LOL...... it goes back Wednesday....

Yes its on the small turbo and the first time I did notice it was in the evening when it was freezing cold, but the car was warmed up. Not sure how its tuned but its going back in on Wednesday for them to have a look-see whats up. Hopefully you are right and with a bit more work these things are eradicated.

Thank Ralph for that

Look I don't want to name names cause that's not fair but it was a top tuner here in Melbourne, so that's what got me wondering why I am having these issues when I'm sure there have been heaps before me. I'll wait to hear back hopefully Monday it's more of a pain in the ass and makes me worry every time I get on the gas.

G'day guys. Just got my FG tuned and got a nice 308.4rwkw with injectors, cat, pwr cooler, PW piping kit, herrod cold air intake and walbro fuel pump. On the dyno there were no dramas, and on the test drive it was just great. That evening, went for a bit of a fang and when I hit boost and a bit of revs I got beeping alarm saying "system comms fault" and "dsc fault". At the same time came up the little yellow engine light. Reading into what I could from the manual it said that is just because of the emissions now not being met. Not a huge concern to me but I wish the light wasn't on. I plugged the xcal in and had three error codes: P0236 - turbo boost sensor A circuit range/performance P0238 - turbo boost sensor A circuit high P0420 - catalyst system efficiency below threshold To me, the first two sound like "well of course you are running more boost now the sensors are reading high" And with the cat one, "well it's a high flow cat it makes sense that it thinks that" Given that I don't want the alarms beeping everytime I hit some boost (which is only 14psi), and that every man and his dog get their XR6 tuned and don't get these errors, shouldn't these have been disabled when it was tuned? A part of me worries that there is a problem with the car but given the fact it was only just tuned on Thu and immediately gave these faults, surely the tuner missed a step? I'm waiting on him to get back to me as he says it's the first time he's heard of those error codes, please let me know if you've ever come across this scenario! Thanks in advance for any feedback!
