Hey guys, im new here i read a bunch about tuning the tbi engines somewhere here i saw someone said that jet makes an adjustable fuel pressure regulator that will increase pressure with the throttle as give the truck gas, all of the jet reg's i saw never specified anything like this i was wondering if anyone knew the model number or could post a link... also im going to order the hypertech power charger later on tonight but ive never seen what goes on top of it, will a standard open element filter just fit right on top? anyway thank you in advance for any replies. btw i did the flip the air cleaner ld trick and its awesome if its nothing but sound its still worth doing.

anyone?? i have a bunch of stuff in my cart at summit and i want to order the rest of my air cleaner assembly haha

Neaver heard of it giving more PSI as u give it gas but i know they have an adjustable regulator and its worth getting

[ChristopherN]

thank you! anyone know what goes on top of the hypertech power charger?

[ChristopherN]

okk i got it i found something on a different site. im going to put an open element air cleaner on it or at least i want to i cant find any with dual stud pacing though everything is single anyone know of any?

Run the stock setup with the power charger and stick a quarter under you fuel pressure regulator, you don't need an adjustable one.

[ChristopherN]

i want an open element filter though, the stock aircleaner housing is restrictive and stupid.

Nope it isn't, it flows plenty for a 305, just mod it some like this:

hmm that seems legit haha not bad for being free idk i just like the look of the open element more and i dont care for having the ram air hose there

[1988 GMC 355]

Well if looks and a lighter wallet is better then a better performing and running truck then go ahead.

[ChristopherN]

so do you know of one with dual studs or anyone here know of one?

[1988 GMC 355]

they do not make open elements for dual studs, you can convert to a single stud though or drill holes to make it work.

kk thank you i wont waste my time looking for them on summit anymore ha

Hes right quarter will work realy good, and u wont have to fool around setting the pressure with it. But if u want to spend the money u can go with an adjustable one. Keep the stock housing and do that mod or see if u can find one off a 95 3/4 i think some come without that pre heater

[ChristopherN]

still do throttle body spacer??

[sepe91]

Yup it will help a little bit wont be big gains though

[ChristopherN]

okk thanks guys i just still find it surprised modding the stock will do better than an open element, ill give it a try

Check out that post out if you havent already there lots of good stuff on ways to mod ur tbi.

A TB spacer will be great, make sure to get fuel line extensions or take to hold down off the bell housing to free the fuel lines.

[ChristopherN]

thank you so much guys

I think you are refering to a vacuum referenced FPR. As vac decreases FP increases. I have read about them in other posts IDK much about them but I've read they are difficult to tune for, and used to get a more stable idle with the bigger injectors.
