TBSS 4L60e to 4L80e T42 Swap

So to clarify, without the blower hooked up, from a STOP it runs just fine? As in no dropping the Bank 1/2 fueling?

Sounds like if this is the case, you simply arent getting enough fuel to the engine. What size are your feed lines TO the fuel rails?

Thats what we figured but the Fuel Pressure never drops???

Can I lose fuel in the rail you think and keep fuel Pressure?

Swap the injectors left/right across banks.

I try that.

Goona run some more NA test before I put the belt back on.

Honestly at this point it sounds like you've done all of the normal diagnostics and then some, IDK what else to say.

Pulling the tank and I'm going to flow each pump individually and together on a bench.

Then I am going to run the same test in the car at the rails.

I'll let you guys no.

Forgot to mention I pull the Boost Regulator vac hose and it will spin all 4 tires now before running out of fuel from the HIT.

Regaurdless of what the gauge says at the rail I am out of fuel.
