Rb25De Down On Power/over Fueling

[R32FREAKK]

hey guys

So im new to the skyline game, bought one a non turbo r32 with an rb25de swap about 2 weeks ago. it drove fine but felt a little slower then expected(thought it was normal as people have told me non turbo r32's aren't that fast). After driving for a week i decided to do a comp test on all the cylinders, it pulled 135 psi on all the cylinders :S i've read that its supposed to be 182 psi, can anyone confirm this? It doesn't feel engine doesn't feel really worn out, it doesn't stutter or have any rough spots, runs and idles fine. Im pretty sure its running really rich, as when i warm it up before i leave work it leaves a marks behind the exhaust on the ground and you get a bit of a fuely smell coming into the cabin(i've checked for splits in the fuel lines there aren't any).

I also find that it picks up faster when i roll on the throttle on instead of flooring it. i have a suspicion that the previous owner might have put a turbo motor in and just taken all the turbo gear off( is there a way of checking if he has done this?).

do you guys any idea what might be causing the over fueling/underpoweredness? is there a way of getting a little more power without dropping a new engine in or getting this one rebuilt?

any info is much appreciated

cheers guys!
