I have the HSW 78mm plate kit on my car and I was going by the jetting HSW gives you, but I believe that is for the stock fuel pressure. I now have the racetronix fuel pump with the hotwire setup and Im just wondering if I should still go by that jetting, of if there is different jetting I should go for on the fuel side. Thanks in advance.

Here is my jets I have...55psi. Listed on HSW website.

75 - .044 (n20) and .024 (fuel)
100 - .052 (n20) and .028 (fuel)
125 - .057 (n20) and .031 (fuel)
150 - .062 (n20) and .035 (fuel)

I know my fp is diff. from yours, but Im running a hsw 150 platekit. I have a walbro fp. the .035 fuel jet was too lean, I upped it to .038 and now it's too rich, so Im playing around with .037 and .036 to see how it does, I would honestly get on the dyno w/sniffer and try the jets hsw recommends and then you can go from there. But that's what I plan on doing to get the a/f just right.

Yes START there and adjust accordingly. It will be in the ballpark, probably rich but a good starting point.

I would recommend reading plugs and not just relying on a dyno sniffer...
