Guess my horsepower/et

Well that sounds pretty good, I won’t be using the nitrous for quite some time so I’ll have the opportunity to tweak it plenty. What areas do you think would be of most interest in tuning
The deep side of the plenum will probably want more jet. My 340 AG with HVH 1" does. Getting a dual plane to flow all 8 holes evenly 1/4 mile WOT takes time and a lot of plug reading.
