TBI tricks ?
 

I have an 87 LWB has a 350 5.7, are there any tips or tricks for the TBI unit to make it perform better or more efficiently. I am looking more for performance that fuel milage. I don't drive it daily so fuel milage is of no great concern.

Not really, the heads wont support more flow with the spiral flow runners, the tbi wont flow much more in the stock config unless you replace the injectors and reflash/ replace the ecm. The aftermarket holley unit gave me no gains, the edelbrock tbi manifold got no noticeable gains and it was all on a new gm crate motor with tubular stainless headers. The stock motor isnt designed for hp, only modest torque and descent mileage and longevity. Sorry... (in my opinion) Cheers- Nate

I was actually referring tips like :

I've been told you can put a quarter under the fuel pressure spring and gives more fuel pressure ?

But thanks for that CHIPS page, I'm gonna check that page out further

Im pretty sure the throttle bodies fuel pressure is adjustable but you have to drill it because GM covered it up although they do sell aftermarket pieces but i've seen a thread from another site where a guy figured it out
