Re: car wont boost over 4 pounds
the turbo also leaks a little oil could thta be a problem?
we put in a dms, resistor box, and an ecu that was tuned on a t25 with dsms on single v, so kinda similar, but still no luck?

I also know some n00b that was impatient putting his cheap kit on, and his first time out it made 10psi on the first pull for ONE gear, then from then on it was ~2psi. What happened? His turbo flange gasket broke in 4 parts, creating a massive exhaust leak.
You *will* come to find a leak in your pipes or somewhere in the exhaust pre-turbo. It could be a warped flange, ripped coupler, bad gasket, crack, or even a bad WG arm that has left the WG flapper opened.

i guess he messed with the wastegate diaphram and it works fine now
