An adjustable fuel pressure regulator..... I plan on doing mods to the engine, but is the one really necessary? Should it be one of the first ones?

I read that tech article about how making the fuel pressure 46psi will really give me a performance boost, but is that true for the TBI? And what will happen to my gas milage?

 

that 46 is for tpi.........tbi runs max 20psi..............and yes if your gonna do mods get an adjustable fpr..... i got mine at turbo city......i can definitely feel the difference between 9 and 16 psi which is where i keep it..........

 

um if your gonna do mods id forget all about gas milage

 

so the stock setting is 9 psi? Is 16 psi the max? and how hard is this thing to install?

 

it is not difficult and it is vary necessary. any mods you wi be doing add air to the engien, when you add air you need to add fuel. so unless you can burn chips an adjustable regulator is needed.
just look at teh DIY AFPR in the tech articles.

stock is 9 im not sure what the max you can run a tbi at is.....mine is 16 because thats all the regulator will let me get , ive got it screwed all the way in........i think it may be because i still have the stock fuel pump too..........im sure ill see a pressure increae with a new 255 gph walbro pump..........
