Injectors? When in boost/VTEC, requires quite a bit of fuel.
Get a professional tuner, such as Jarrod said. If your doing what I'm doing (fuxing with crome and learning your way around the program) start on an all motor car first. Less likely to break shit.

I'm the one tuning the car guys. Its not a fuel issue. Its having ignition misfires as soon as the boost goes over 5psi or so. Plugs are gapped pretty damn low. Its an issue with the ignition system. The spark is too weak to bridge the gap on the plug after vtec crosses and lets in denser air.

You'll see my hatch after I build the transmission and other stuff. I'm hoping for close to 500? 
Make it happen Matt!What all have you guys done/tried?
