power..... what size turbos?

Nelson Performance

80mm, 1.1 exhaust housings, kind of a mid frame sized turbo

without a doubt there is lag on the street, but it's purpose is highway fun.

still makes enough boost in 1st gear to boil the tires.

btw, the holley efi system turned out awesome on this truck.
customer has it and is enjoying the power.

Do they still use factory ecu for anything? Will it pass obd scan for inspection?

Nelson Performance

Sure did.
We kept the ECM for many reasons.
Cruise control
AC
PRDL functions
Bcm comm
Starter engagement
All gauges
And quite a bit more.

However the factory engine harness was slimmed down to about 10 wires; just the essentials.
