stock FPR or do I need to upgrade?
 

So my weak GSLSE 102 LPH fuel pump isn't cuttin it anymore. Definitely leaning out at top end. Bought a Walbro 160 LPH pump and now my only question is now that my new pump will flow more, will my stock fuel pump regulator still regulate the same pressure or do I need to remove, block off, and install a aftermarket FPR?? Thanks.

no ideas huh?

Dont worry about it... I changed the pump on 2 -SE's to MSD models, the stock regulator handled it well. I have a fuel pressure gauge in the car to monitor, so i can tell you for sure that there were no issues.
