Plugs and Fuel Pump
Ordered my NGK plugs and Supra Fuel pump should have them installed by next week. Going to do a .022 gap on all the plugs. the Supra hpfp should be a good addition, at wot the car is having some lean issue with a lot of boost so this should clear it up. Will need to send some logs over to JB4

Hey, do you mind posting your full set up?
Just curious at what stage the supra hpfp would benefit, whether it be for stock or if its because you are stage 2 or something. |

No it's not - there is a pressure regulator that will keep the pressure the same, the benefit is that the TU pump flows more fuel per pump stroke vs. the Gen 1. pump. So when demand goes up there is more headroom in the fuel delivery thus it keeps up the pressure better.
