HI! folks, a correction to my previous thread on that tbi unit. It is a slim lined injector tree with physically smaller injectors for more air flow. I e-mailed them with a couple of questions i.e. if I'm running 14 psi mow, What do you recommend for fuel press? with your set up & can I run a tpi pump i.e. 85 corvette. Waiting on their response. If interested injector set up w vac regulator is $289.00 without reg $189.00 eBay item numbers respectively is #252871869017 & #252865497725
