Doc, Rob also told me to start at 58 and move it up as required.

Wish I had a good dyno near me. I have meth kit I won't install, and A/F's borderline....and not much we can do right now. Need to get up to Chicago and get some things done real soon. 1/2 mile event will be here before I know it....thanks for the update...

With the NW DCAI you will be getting more air than me. That will get you leaner too....maybe?

Before I installed my fuel regulator, I installed the extra gauge in the engine bay and with the stock filter-regulator but with the SL55 pump, I was reading 58. I need to get a hose to connect the vacuum line and then I will be finished with the install. For some reason my regulator came without any hoses or clamps whatsoever. Fortunately, I had some fuel line from an old regulator that I had lying around, so a trip to NAPA and all should be well. Good to hear that we may not need injectors, that will make my day.

I am at 65 psi fixed. I am not sure that is relevant to you... But anyway, there it is.

I'm running a 65mm pulley, single CAI, and about to install NW Manis and a SL55 pump. Low Texas elevation. I was going to replace the stock filter with a new one while installing the pump. Now I'm wondering if I might need to go with the un-regulated filter and separate regulator. Not stacked, but I'm thinking I may be borderline.

For the 65, history would say you are fine but if you ever go smaller or stacked you'll need more fuel. Its a whole lot easier to do it all at once than going back and doing it again. Then you can dial in the pressure as well.

Can someone send me the instructions for the nw fuel mod? The srt 6 I bought has it installed and I'm about to put on new manis and go from scai to dcai so I want to know as much as I can about the system.

These are the instructions I got from Rob at Needswings:

1. jack up back of car, or just reverse it up onto ramps
2. remove black plastic shield covering fuel pump/filter
3. remove oem filter/regulator, wear glasses as fuel will spray when you remove the first line
4. swap in new filter, line from pump goes to the filter in,
5. line from out on filter goes to the regulator in either 3 or 9 oclock position, flow can go either way
6. line that went to tank on oem filter goes to the bottom port on regulator
7. install gauge onto face of regulator, use Teflon tape or paste, I prefer paste
8. small vac line from oem filter goes to small port on top of new regulator
9. mount new regulator to underbody bolt with supplied aem bracket
10. zip tie up the excess lines to secure them
11. have buddy turn key to on position without starting car, while your underneath watch the pressure gauge and get the regulator to 58psi
12. start car and verify pressure setting while running, the car will chug a few times on initial start up while it purges out the air bubbles
13. check for leak, recheck for leaks, after test driving check for leaks again, once all leaks are tightened up put the plastic shield back under the car and enjoy.

I have those mods(minus the pump) in Austin and have no problems.
