Gday fellas I have a lower and upper intake manifold along with a larger throttle body this gear is only off a 220 so its not a major upgrade.If I put these on my motor will it change the tuning greatly I cant find a dyno tune place that will do an au.If I put the throttle body on will it affect the tunig at all,have any of you guys used a flash tuner and what were the results? Thanx Freddy

youll need a tune.

flash tuner is the bees knees in tuning really. Id suggest stock piling all the mods you plan on doing and fit it all up and get it tuned at once.. saves on dyno/tune time

if i go for any more mods, ill buy a flash tuner (my xr8 is pretty 'mild' tho).

Gday again thanx for your reply AUIIPURSUIT I have rung numerous places up this way no one I have talked to has the software todo the tune on AUs and they dont know anyone that does I have all this gear to go on cant find anywhere to tune it,thats why I asked about the flash tuners! What bread of flash tuner would you go for?

SCT is the most common and most widely used for our vehicles. It would be worth the drive to Sydney, a lot of switched on guys there. Spiro at Autotech has done many members cars on here. Give them a call.

I disagree - I think it will run fine without a tune.

The manifold will be the same as what you have already so the only real difference is the throttle body, on my old XR8 the TB was changed to a 70mm one with no need for tuning.

I am assuming you are putting this gear onto an AU2 XR8 going by thread title?

Blacktrack at Thornton is the only local tuner with any type of software to tune AU's. Justin has SCT. Next closest to Singo is Tamworth IIRC. You should get the full list from Rob Herrod's website as he is now the national distributor for SCT. CAPA used to have a list of dealers when they were the distributor.

Other than SCT, Sniper (from BPT Motorsport) works with AU's, as do J3 chips from TI Performance. I think there may also be a workshop on the Central Coast that has either or both SCT or Sniper. Moates Quarterhorse also works with AU V8's.

IIRC both Herrod's and BPT are commercial sponsors of AFF, you can contact them via the commercial sponsors' forum.

OTOH TI's J3 chip and Quarterhorse are tuned with freeware, so any dyno shop with experience with LS1 Edit, VCM Suite or any of the aftermarket ECU's should be able to tune your car with downloadable software that runs on their Windows laptop.
