have the turbos clocked wrong. The stock pipes wouldnt even fit with those like that. BTW ive been using an Ashspec zemulator for three years now. The only problems ive had with it was me when i first installed it. Several boost leaks and a pinched oring on the injector caused the problem. Once all of that was fixed his tune has been running fine with an AFR of 10.6 to 10.8 ever since verified by an AEM wideband on each downpipe. Im ok with that since its safe and there is no detonation.
