Need to be educated on fuel system upgrades
Getting ready to have my Maggie 2300 TVS system installed. The tuner told me if I considered E85 I could see 35-50 rwhp. At first I was thinking $500 for LT4 injectors, $800 for LT4 HP pump, and $300 for a P&P E85 kit was a bit much for such little power but still thought about it. Car is my commuter and I have a C7 thats blown so not looking for a dyno queen. Truth is I dont want to mess with the fuel economy to bad. My question is this. Are the pump and injectors just plug and go with a tune? Do I need a Aux pump or anything else?

You will need a low side for E85.

Then if you want to run E later just add a flex fuel sensor kit from DSX our JMS fuel pump voltage booster and retune, We typically see 10% additional Rear Wheel Horsepower over 91 octane on E-85 Ted.

Is the LT4 setup enough to run more than the standard 7 psi of boost most kits start out at?

Of course it is. That's the entire point of upgrading to the LT4 fueling.
