Hello all,
Dnt knw if you talked about it in another thread,, but here I go for it again if it's the case. How efficient you find an boost controller gauges ? my friend puts one on his mi16, tune it to 4bar, he got better torque.

eh? surely you mean an adjustable fuel pressure regulator?

Yes that's it !

ok well, there are those FSE regulators that are "rising rate" but that actually
only means they can give faster response from closed throttle to full throttle
but if you actually increase the fuel pressure, the engine will be overfueling,
just as with larger injectors...

does it give some bhp thought ?

Only if the engine is running lean to begin with, like with dirty injectors.

i am also thinking about FSE power boost valve. Because i want to have better throttle response. Somebody has it in his car? Because there is va lot of theory and marketing on net but nothing practical. So what do you guys think?

doesn't do anything really, from what i have seen/read over the years.

wouldn't it be better to tell your mate to run a bigger cam if he wanted more torque??
