Boost Questions

[top8fan]

Can anyone help me with my boost. Installed guages and boost only gets to 18 at about half throttle and 25 to the floor. Also when the tranny shifts the boosts drops to about 10. Is this normal??

boosting to about 25 isn't bad at all for stock.

trucks not stock though, my info's not coming up. It has a cold air intake, stock exhaust w/cat and muffler delete, banks 80hp chip and a boost tube.

What year truck, what size engine, are you running any tunes. Those will all make a difference on what your boost will be.

I would say your truck is running normal.

Thanks. 2000 Excursion w/7.3 psd. No tunes yet

If you are at 25 then you have either a chip or a tuner.

sounds normal to me. i can hit 30lbs of boost with my chip all the way up but i also have a pre turbo exhaust leak so i could have a little more boost but. i wouldnt go much over 25 with the stock turbo

With my stock late 99, all I'm seeing is 11-12 @ full throttle. Judging by your #'s I might have a leak somewhere.
