30 psi sounds kinda low, should be a little higher at idle and then jump close to 40psi when you hit the throttle good. What kind of car is this in? Maybe possible that the map and tps plugs are backwards? Injectors with no resistor box? What ecu is it running in conjunction with?

90 dx, with resistor box dsm 450's pr3 ecu stock 02 sensor not hooked up (problem maybe? ) also sounds like my car needs some plugs, hasn't ran for 3-4 months def when it gets warmer ill get some good gas in it change the plugs and play around a little more with my tune'n

it might be some problem with wiring of the ground connection. afcs have two ground connecters and if you place them too close on the same ground line, all the sensor values can be read off a little.. so -%50 wont act as really -%50. check your sensor voltages through the afc if they are right around what they should be
