I understand your points dont get me wrong, ESPECIALLY if you have spent XXXX on a build, go standalone. But an EMU is in keeping with a 80quid second hand td04/05 or a 100quid IHI turbo.... for the fellas on a tighter budget. I get your point that guys running 800hp supras arent likely to be running a piggyback, but then they arent getting there with 2nd hand stock turbos from 2.0turbo cars? Its a whole other playing field and a whole other budget. But just to reiterate as previously mentioned, standalone around the 600quid mark that your tuner likes is the way to go over spending 550 odd on a secondhand EMU. but if you can grab a EMU for 250-300 and it does the job with your 100quid turbo strapped to you forged engine (which still probably has a stock inlet mani, cams, valvetrain, crank, end caps etc) and it suits your budget then i wont call you stupid for one second. But D3NO might lol Lots of love and jokes.. Phil
