is 80 excluding parts a good price for a dyno tune?

very, is that a power look? or a tune? most shops will charge by the hour.

What does a power run only usuaully cost .. ie, how long does it usually take? I know tuning can take hours...

Power runs I used to get for either free or 30 bucks etc. Normal Price was about 80-100. Power run doesn't take too long, its basically getting your car on the dyno, strapping it down, and then giving it some strap, they might give it a few runs. Probably about 2 Minutes at most once its on I guess. I'm pretty sure they check to see if you'd run lean or not too.. My local dyno shop is shutting down so. I'll have nowhere to go.

Power runs typically cost $70 odd dollars, in Newcastle Workshops anyway. i.e Impact or Scots Dyno Tune Graphed against either Speed or RPM. Mick

I paid $80 for a tune and power run.

$30 dollars for a power run at EFI Dyamics in Lilydale which will check A/F Ratios, do a few runs, and play with a bit of boost as well - depending if Errol is busy or not (weekdays are the best time). Thats a mates rates price, but i think for every joe its around 50 or so. Not much tuning can be done on stock ECU systems. You can play with the AFM, but if you lean out the topend with it, the bottom end will be leaned out as well, hence you run a risk of causing damage. AFM should be set to 380 Ohms by adjusting the screw and putting a multimeter to Pins 1 and 6. Good idea to go and check your boost levels and if there is any pinging to an experienced tuner/dyno operator.

The screw is only really good for calibrating Closed Loop Control. If anyone honestly tried to use the screw to tune their car I bet they would be the same type of people that would put a resistor on the water temp sensor to richen it up as well Mick Some original photos have not been recovered yet.

Got old thread much?
