i know what a fuel pressure regulator is, but ive only been into cars for a years and so fucking sorry i dont know what a rrfpr meant dick head, this is the point of the forums, to learn new things dumb shit.

the fact that u sit there and had time to redo the pics when u dont even know wtf ur talking about is sad,

i added a tre 255 fuel pump today and now its not having the shift issure, so more pressure helped, but now it takes alot of cranking and pedal play to start? its driving me nuts

not looking lean

how do you have a turbo build and not know what a bov does or what a rrfpr is?

Not trying to be rude, but i would think research would be the first thing to do on a build

[custom e30]

ok will check it out tomorrow

[matt0300]

5 pounds off boost shouldn't be a bov problem, really? It could be a fuel problem, take out a spark plug and see if ur running lean.

[custom e30]

no

[jrdeamicis]

No tune?

ok got yea, and how much for injectors? and where u located?

explain how it would be a blow off valve prob?

When you execute a shift the engine has to drop from high rpm to a lower rpm. The turbo will be spooled up from high rpm running and will be delivering more air than the engine can use when it drops to lower rpm. The blow off valve should should relieve that excess pressure. If it doesn't, the engine will momentarily be running too lean.
