Fuel Pressure regulator

This is very interesting GZE information, but here we use 4AGE tech. Yes, these Weber regulators are linear. The filh can use the stock pump because he cannot produce over 140hp NA only with regulator/breathing mods (without race camshaft). There is no problem to run 2.2 bar on idle also - no way to produce any "lean" problems.

"Set fuel pressure @ 3,0 bar at idle, raising to 3,5 ber when on full boost."
"Target is about 3 bar at idle, and 4,5 bar at full throttle, that will raise compressor boost from 0,86 now, to 0,95 bar... "

There is only 0.5 bar fuel pressure increase for 0.86 bar boost increase - this Malpassi regulator even is not linear !!! Very strange !
I will expect "target 3 bar (at idle with VAC~2.5-2.7 bar) and 3.8 bar at 0.86 boost".

PS: If you plan to go turbo with just a fuel pressure regulator mod - you MUST use rising rate regulator, but I prefer to go aftermarket ECU and linear regulator instead...
Info:7MGTE in-tank fuel pump is 100% compatible to 4AGE one - and I already bought one to replace mine. Keep in mind that 7MGTE is 230hp stock.
