is 15psi boost normal or low??

[SCDEALER]

2002 7.3 pretty stock intake and a edge evo 2 on a tow tune (only thing i can say good about the edge is i like the small pod with the 4 function guage setup).

i pull a 13k trailer and under hard throttle it will build 14-15psi boost. Is that correct, i know on here i see a lot higher numbers. the truck pulls good.

i have checked all the clamps on the intercooler and they are tight, no smutt around them, dont think i have any leaks in them. looked at the y pipe in the back of the turbo where the exhaust feeds in and it is clean and dont hear any exhaust leaks.

thanks Fletcher

I'm pretty sure your truck should be pushing 16psi stock. You might have a minor boost leak somewhere. Get you hands on a boost leak detector, or you could probably make one yourself & give it a quick check. Might be an IC boot or something starting to loosen.

sounds low, i know with my truck stock i was hitting about 21-23 PSI

21-23???? I'm not trying to be an azz, wriott, I swear! But are you sure about those #'s? Just wonderin'.

get a banks or bd wastegate bd's come preset and you can adjust them to get 30 psi tops for a stock turbo also turbos tend to leak around the compressor wheel housing so when you get the wastegate make sure all the bolts are tight they tend to loosen over time

yeah, not 100% stock, i had a boost fooler on so it didnt defuel. now im able to hit 33-34 with the mods in my sig

no problem, actually it made me think about it a little harder and i rememberd i had the boost fooler installed as i did it the same time with gauges. i didnt have gauges in the 100% stock form so im not sure what it is at stock but i would thing it should be near 20 or so

Stock's 16psi. With or without a WW or Banks wheel.
