I've met the guys. I am from Houston, remember.
Duy built that car. The guy you are referring to tuned the Haltech. Duy built the motor in his garage. He put together the turbo kit. I remember when he was putting it together, because he'd call Chris May sometimes when I was over at Chris's detail shop...and they'd chat about stuff. Duy was asking about buying the injectors and fuel rail through Chris, because Chris has an account with JWT. They decided that the discount wouldn't be worth it, because they'd have to ship it twice.
And you won't make 300whp with a T3/60-1 at 10psi without Nitrous. I wish you could. I have been down that road, twice, once with Duy's help...
