Easy way to under stand the way fuel, for every bar above atmospheric pressure you should need 100 percent more fuel based off VE of the motor
So 1 bar (14psi) 100percent more fuel 2 bar 200 percent more over atmospheric. Boost compensated tuning is based off this theory and works very well

Re: LST / LS-T Turbo B18A B18B setups
I'm not super educated on fuel systems but how does a boosted condition RAISE effective fuel pressure of a pump? I thought it was actually the opposite....I.e. When at vacuum fuel is basically pulled from the injector and under boost it basically wants to fight to push fuel back into the Injector. This is what must be accounted for in tuning by increasing rail pressure to accommodate for such a condition under boost. That being said, isn't the raising of fuel pressure under boost a product of the tune and user parameters rather than a function of the pump and equipment itself?

Its really nice to see a Reaper take that much abuse, and continue to repeat the same progress flawlessly. Welcome to the 'Temple of VTEC'

Nice man, looks like they make a good product indeed. I finally decided to keep and boost my B20V SI and just last night I picked up a Full Race Prostreet manifold and GTX3076R .82 a/R . Today I'm going to shop around for a gate and front mount/piping kit and then figure out whether I want to go ID1000s (gasoline) or ID2000s (e85) and have a downpipe fabbed up and then I will be bringing her out of storage to start the install! I'm hyped! Nice build again tho man, keep up the good work!!

...well I have 3 fuel pumps so fuel is not so much an issue..I run a radium engineering dual pump surge tank, with two stealth 400 fuel pumps..and pump gas, will be adding meth injection soon...going to make 500+on pump with meth and with c16 7-800hp..

Re: LST / LS-T Turbo B18A B18B setups
It's cold in oregon e85 is too cold of fuel to run and to inconsistent as my tuner put it..my friend has an Evo on e85 won't start on cold days here...and I run a full DEI fuel chilling system and intercooler sprayer...so I can chill pump gas and create denser fuel...
