help Redtop Sr20 giving 5psi ,,,

[deathBooster]

I've been trying to figure out why is my car giving 5psi only. stock sr20det should give 7psi...?? could the boost gauge or turbo timer readings be off?? BTW.. I am pretty sure there is no vacuum or turbo leak...

I have a stock sidemount intercooler, 3" downpipe plust 3" catback but the stock ka cat converter.. could that be the posible cause????

What are the list of things I need to mod to max out the stock turbo (T25)? I have a Z32 maf with the modified ECU sitting there, Dont really know if I should install it or not.. need opinion...

where did you T the gauge to?

Don't install the z32 maf unless you get bigger injectors and a bigger turbo. It could be that you have a small boost leak.

what kind of boost gauge do you have? Are you sure it's not reading .5 bar(which is about 7 psi). If not i would check some of your connections.
