Had my AUII Fairmont for just over 4 months now & decided it's time for more power. Considering 2 options, new exhaust - at least extractors, or powerchip. Has anyone had a powerchip installed and if so what was the result. Advantage of the chip if it works is it can't be seen when you pop the bonnet like extractors can, so you can keep the mod secret from the insurance co. Anyone who's done the exhaust, what was the result.
I agree with everyone else, chips are a waste of money on standard(ish) engines.
The standard ECU works very well indeed on the standard engine, and even when mechanical modifications start, the ECU copes quite well.
It's only when serious engine upgrades are made, you may need a chip and some dyno tuning.
The standard exhaust and manifold, OTOH, are complete garbage and don't flow very well at all.
Extractors and a decent 2.5" system will give you at aleast 10kw more power right across the range.
