I have a Tomei Fuel pressure regulator, on cold start gauge shows 2.5 bar when the car gets warmer it drops to around 2.0 bar, im planning to raise boost to 0.8 bar, so today i tried to raise the fuel pressure but its not rising its sticking to 2.5 bar, it is able to decrease pressure to 2.0 bar but not increasing more than 2.5 bar, does it mean i have a weak fuel pump or a bad FPR ? fuel pump is 100lph.
Recently i had blown piston no. 1 while running 0.7 bar boost, i don't know why did this happened coz of running lean or i've doubt the timing was advanced too much from distributor by a mechanic.
