As VR CALAIS said ya cant go past electronic automotive
got mine done there very happy there gettin some really
good cars out of there now with good power read outs
electronic automotive did my vnss when my brother inlaw owned it, was good.
since i owned it john and danny made it run amazing and never misses a beat. good tune makes a big difference that alot of people dont realise even in 5 litre's.
just head down there to bresciani's or leave a msg on johns fone he will get back to you he is always flatout, always bizi im about to take my vn down there now as injectors causing a miss and running crap was worried i hurt the pistons but all good.
the guys have done just asmuch 5 litre's then turbo's, remember john was racing 9 sec v8's for a long time before he took off with turbo's.
