high ltft on new swap Hello everyone. Hope someone can help with a new swap startup concern. Car runs ok but have ltfts on both banks of -15% from idle to 2500rpms. Codes p0172&p0175 are present. Checked fuel pressure and sure enough running pressure is at 68psi. I am using the wix 33737 filter regulator.I am aware that the factory presssure should be at 58 psi. Is there a more accurate unit than the wix brand or must I ditch this and run a adjustable bypass style regulator? Any suggestions would be appreciated.

I run a GM filter. That being said, they are ~$100. I actually run 2 filters, 1 stock s10 filter before. I change the cheap s10 filter out, and keep my GM.
You can go either way. If you have ANY intentions of doing anything more performance oriented, you may as well change to a regulator. Other wise, your just throwing good money after bad.
You could also change the tune, but thats really not a good viable solution, when you know there is a technical "problem".
