with boost I would have ran bigger pipe and definitely get rid of the 40 series, the chambered design doesn't respond well to boost and restricts ALOT of power.

How much PSI are you pushing?

I dont think a gas motor can sound like this with the flip of a switch. DSP5 EFI Live switch. Go from stock to 500+whp and choppy lope in seconds. LOL

I've had my fun with several LS powered rides, but I'm addicted to Diesel now.
That's just the injectors giving too much fuel and then bouncing back on the governor spring to keep it at idle. Like a 'higher power potential' mode. This only works because diesels build so much more boost than gas engines, and this gives it more fuel to compliment the boost.
Soon gas engines won't even have a camshaft, but just a bunch of valves and solenoids and a computer that changes valve timing per RPM to keep it at peak power at all times. No need for a switch

Dyno sheets and graph up.

Need a bigger fuel pump. Fuel pressure started dropping around 11 lbs of boost.

Because of this, were just going to shift at 5500 for the time being until i get around to throwing in a pump capable of pushing enough fuel.
