Not that I don't trust whoever is tuning my truck. Just curious what you guys are running on fuel only trucks with strong rods and pistons. On your balls to the wall tune for a big turbo or stock. I'm probably the only idiot with a built motor and a stock turbo though lol

You're not the only one with a built motor and stock turbo. I run about 2200us to hold higher rail pressure

Anyone with a lot of dyno'ing care to share which is most important - pressure or vol (ms) or where's the general break where your losing power if pressure goes below X amount?

Obviously full pressure is ideal but I'm just curious what one would do to maximize their fueling if they're limited by smaller injectors?

Think I'm going to try 28 degrees timing with 2425 (what I've been running) with a 115-120 fuel shot.. sound like power, or one big disaster to you guys? Too much timing?

im running roughly 3100 on stock sticks. however with that PW i can drop the rails 3000 psi. Anyone have a clue how much i should drop the PW to bring the rails back up to 24,000psi? Its either drop the pulse or buy dual fuelers :D

How bout an LBZ pump with the modded fpr? Should be able to hold rail at that PW with 3100us with stock sticks, My LLY with stock pump and a lift pump will hold the 23500 its calling for in the tune with my stock pump with 93K on it. My plan is to go with an LBZ pump when this one starts to fail.

It depends on turbo and pump ungrades. If you got enough air to support the fuel or not.

another stock pump would just bandaid the problem. It would only be a matter of time till the lbz pump got worn out. Plus, i can throw another pump over my existing one in about half the time it would take me to dig into the valley. And i have plans for 100 overs later.
