Default Few questions!!

I have a bolt on 00 z28 and my oil pressure seems low to me around 20-25 at idle. Also when im at a red light and it drops to 20 it kinda makes the car sputter. do yall think its new oil pump time??

My other question is do you lose low end torque when you install a full exhaust?

I've heard that if you run with open cut outs you lose some low end torque but I'm not sure. I believe it has something to do with backpressure.

I believe you kinda got it backwards. Your oil pressure is dropping because your car is surging(trying to cut off). Clean your MAF and see if it helps out your idleing problem. Your oil pressure increases with RPMs doesn't it? Whats is it a WOT?

Yeah it increases whenever i give the car gas i think the car was running funny because of an o2 sensor. Also the wot pressure varys it can be 60 sometimes or more than that.
