Low boost and dropping
I finally installed a boost gauge today and found that my evo 5 is only hitting 13psi and then dropping off to about 11psi at around 6500rpm. It's got a turbo back 3" exhaust and free flow pod filter. I thought boost doesn't drop off so much with a full exhaust?
Isn't this quite low for factory boost? Wondering if I install a boost controller if it will hold higher boost, or if something else is limiting it?
Cheers.
