I am gonna spray tomorrow on my Torquer 2, TSP Tune, TSP LongTubes Corvette. I am only shooting a 100 shot through a NX shark nozzle wet kit. I am jetting it for 52n and I don't have a 28f but I have a 26 and a 30. As I was told the timing is allegedly supposed to be fine to run a 100 shot on, but I was thinking about just going with the 30 fuel jet rather than risk it running slightly leaner than it normally would have.

Anyone have any input?

 

I would err on the rich side. Your not talking rich as sin so there is no worry about the cylinders washing out. Now if your tune was fueling it rich already maybe go with the 26, as NX generally jets on the rich side from my experience. Post up your times.

Your running TR6 plugs correct? Gapped .035-.038"ish? Check #7 plug after your first run, look for tell tale detonation on the front face of the plug, which would be a "chunky" appearance, as well as speckles embedded on the porcelain. #7 will almost always be the most problematic, followed closely by #5. Good luck man.

I would also err to the richer jet. I am tuned for NA at 13.0 all across and when I use my 150 shot on NX recommended jets of 63/33, AFR goes down to low 12's to mid 11's, so it is jetted a little on the rich side.

better safe than sorry.
