Flexfuel pump swap into non Flexfuel NNBS ???
#32
***** Update ***** ac delco part # MU 1847 is a direct fit in my 07 NNBS VMax. I just did the swap tonight and its plug and play. Took it out for a test drive and the fp held solid.

I have no idea. I just know that my stock pump dropped more then 15psi during a run and the new pump held steady at my 500 rwhp. I'm going to the track on Saturday and I'm turning up the boost. I'm hoping to see what my small turbo will do with my 6.2.

I was going to update this as well. I had my down pipe welded to my factory GMPP catback today (ridiculously quiet now) and on the way home my trans was surprisingly holding a good amount of boost without slipping. I turned the boost controller a little, rolled into boost and at 10 psi my fuel pressure was rock solid on 58 psi.
