ok for starters the toy shop is your only hope for parts in newie area bit pricey but they will negotiate if you know what your after and what its worth, never had problem with larry moe or curly lol, ive bought quite a few parts from there at reasonable prices ...and i don't think you will get anything done there as they are importers of cars and parts basically wreackers for jap imports.
ADNUM automotive is hunter dyno may be worth looking into them they tune some reputable streetmachines If you want or need any engine work done Jack Jones engine reconditioning in lambton you'll have to pull the motor out but he's a ledgend this old bloke and a wealth of knowlage when it comes to screwing together a weapon of a motor he's the only engine builder i will recomend. For tunes and other modds
PBE DYNO TECH there at sandgate in newcastle, ive had work done there they'll do anything and if they cant they'll track down someone who can they're a good bunch of blokes and cheap labour.
JOHN COLLINS DYNO he's at broadmedow and i recomend and say john and nathan would be one of the best atm in newie, his son had turbonetics at cardiff when it was open so i believe.
SKAZZAS DYNO at cardiff only been told of him,
TRG AUTOMOTIVE in cardiff i know people who have had all sorts of modds done here with no complaints. and BLACK TRACK PERFORMANCE but use them as a last last resort never been there but i know people who have and they have been happy with the tunes they had done but they fkn strange that place, when you can get them to work on ya car which is hard to do they can do a good tune but they are expensive .
at the end of the day no there are bugger all tuners in newie but if you know the right people to ask for advise theres no problen at all getting a ecu reprogramed here in the newie area .
