well....
i got my car back from being dyno tuned this afternoon.. unfortunatly not quite the result that i was expecting.. there are still a few issues.. first issue is what seems to be a possible boosting problem?? its not hitting 10psi.. at all. and the ba xr6t injectors are still over fueling with heaps of fuel pulled out while being tuned. and it was suffering a little wheel spin on the dyno which may contribute to the result.. anyway the result so far is 175rwkw  and 520nm torque  ..on the cms mainline dyno which is know for not being generous with its results..  so in a week or so ill be fitting the std au injectors, and re dyno'd and tuned.. i think it can get a fair bit more out of it.. as before the tune, while it was pinging and leaning out it seemed to have a fair bit more grunt than it does now.. |

175rwkw is nothing to turn your nose up at
, but i agree you should some more out of it.hope you get a better result after swapping injectors etc. Josh |

Troy, i had the same problem a while back. Try the TL magna 4cly injectors. There bigger again than the au, pick and steal more has miles of magnas. Your running a rising fuel reg yeah? what ratio? Have you upgraded your fuel pump?
Sorry can't be bothered reading back and i can't remember Oh btw its 7 deg BTDC, not ATDC. Had to rub it in

OH, and i used a brake booster one way valve to cut boost pressure to the map. You just need a really tiny bleed hole to let the vacuum vent between it and the map, cheap and effective solution.

Had to rub it in um no rising rate reg just the au vct reg. and the fuel pump is a walbro 255. actually before the tune i had to set the base timing (el ecu)at aproxx 7 deg atdc to stop the pinging..thats right after..  not before..lol now the base timing is set to factory with about 5 deg removed under boost.. |

HOLY f**k!!!!
It wouldn't idle at 7deg, i think your balancer may have slipped cause at that reading the piston would be have way down the compression stroke before full ignition. What ecu do you have? maybe consider getting a rising reg for that extra fuel pressure when your on boost.

you would think the 20lb AU injectors would be running maxed out with a boosted 4L ?

So how is Joe tuning your ignition for boost? Are you running a J3?

Is it any good troy? what did it set you back? Shame it can't run the big injectors though.

Shame it can't run the big injectors though. the smt6 was about $450.. ive read some good things about it and it seems to be very popular in europe.. and it can be tuned on the fly via laptop computer..much cheaper than the chiptorque chip n tune.. at the moment there seems to be no need for the bigger injectors as he is having trouble with it running rich.. ive also got a new set of 36lb injectors aswell although i might have a short somewhere because as soon as i turn the aircon on the engine floods and stalls  so ill go see joe tomorrow and see whats going on ....
