Is the AU V8 Tickford ECU any different from standard power wise? Best place for ECU tune.

[XA Coupe 666]

I bought an AU V8 to get the GT40P heads & inlet manifold to put in my NF Fairlane.

I did a std rebuild on the bottom end, put a custom mild cam in (To use stock convertor) & 1.7 Crane roller rockers, larger inlet valves, pocket ported & shaved heads to get 9.5:1 CR, 4 into 1 headers\extractors, lager exhaust, std injectors & throttle body. It goes & sounds good.

Haven't dynoed it but it should be up around the 220 mark (Crank) same as the Tickford but here's my question;

Was the Tickford ECU modified for more power?

Would it pay to get it tuned & by whom in the Ballarat\Geelong\Melbourne area?

Being a 96 model I would have to put a mod chip in to change settings, yes?

What sort of money are we looking at for what sort of power gain (Approx)? Will it affect mileage greatly? That said I have LPG injection too so mileage isn't a big thing.

Thanks
