If you want to squeeze every last HP, that sounds like the way to go! Impressive numbers over the Bisi.Hytech is the way to go for D16. Of course John will charge you 1500 and take 6 months to build one. But is does work. Picked up 10lb torque and 8 hp up top over bisi.
Ran Fontana about 2 years ago. Won STS. Never liked driving to LA area. Hytech was on Wongs car if you know him.
Where you located? Yeah, I know Wong's car. Mine is actually Lugod's old car.
