Only way not to be at this power level is add a cam with a lobe upgrade or install the lt4 hardware

I know you're close to maxing out the stock fuel system but one 15gph nozzle should do the trick. I think the AFR needs to be tweaked a bit. You don't want to be dependent on meth to that degree.
If it were me, I'd bump the initial pressure a bit, be sure the turn on is at 3psi and set the gain back to around 6 AND go back to one 15 gph nozzle. Then get a retune around those parameters. Now you have your own wideband and can watch over things closely.
One 15 gph will spray 5.33 fluid oz in a 10 second pass.

As Fyreant knows, his meth kit at 8 with 2 nozzles is compensating for a lean non-meth tune. The right way to do it, as he knows, is to properly tune it to .8 (rather than .9) lambda without meth as good as he can, then introduce the meth and finish up. You end up using less meth and more gasoline but the results are not really going to be any different though. Where he is now with PE fueling, he needs a screw but has a zip tie.....
I have some nice screws in my laptop bag but there's more licensing fees to pay and his tuner can do it for free.

Like TA said, if you are a little dependent on meth, you are 100% dependent on it. Doesn't matter if you need one or two nozzles, if you're out of fuel, you are out of fuel.

I would say so! Still need some adjustments to the tune but overall its running MUCH better!

I may be getting together with my tuner tomorrow evening to get my tune adjusted as needed. Then it's go time for the drag strip on Saturday morning! Stay tuned!
