Data logging questions?

So I decided to check my fuel pressure with a Mac Tools gauge and compare it to a gauge I bought from CFM Technologies. The gauge from CFM Technologies was totally different from my Mac Tools gauge. CFM Technologies gauge reads 13 psi and my Mac Tools gauge reads 17 psi. I am guessing this is why my readings are off on Tuner Pro. I bought a Fuel pressure regulator from CFM Technologies and I can not get it to drop bellow 17 psi. So can I run my TBI at 17 psi? Maybe change my BPW? Will I have problems with this high of pressure? I took it out and it runs good. I am getting close one my VE tables. I am running a stock International 345 with stock TBI , 65lb injectors, tri wye headers, fuel and spark control.

Thanks,
