walbro 450 install question

[Syclone#2960]

Thinking about upgrading my walbro 255 with the 450 in my V6 typhoon.
Is this pretty much a bolt-in upgrade??

I had no issue installing it on mine, I switched from a aero 340 to a Walbaro 450

Curious on why you're thinking about upgrading to the 450 pump. Want to get rid of the meth for E85?

Turns out my tune (fuel table) is way off. Not happy about the dyno results...somewhere along 350/500 awd dyno at 24psi. asking for more fuel.

Sounds similar to my Ty. I ran 23psi when I went 10.71, was maxxing out the injectors over 100% DC. I'm not spraying that much Meth either, have the Alkycontrol dial at 4.5.
