I have a built turbo D16Y4 non vtec getting dyno tuned as we speak. Full build list is on my previous post. They have hit 160hp @10 psi on 98 octane. Bumped it up to 13 psi and no power increase. Not responding to timing either. What’s going on???? I’ve read that timing is critical (and a bit special?) with these cars, could that be the issue if the tuners aren’t familiar with this? The tuners I have taken it too are the best in my area with a good reputation, although they haven’t tuned many (if any?) turbo Hondas before as they just aren’t that common here in Australia, especially where I live. Any suggestions would be great.
