f14 w/ nx 100hp results :( Made 478rwhp and 466rwtq w/ 100hp NX wet shot. NA numbers were 397rwhp and 376rwtq. Have graph if anyone wants to host it for me.
For some reason Allan couldnt get rid of the surging problem. He tried many things like -plugs(different heat ranges)
-swapped plug wires
-tried different plug gaps
-swapped coil packs
-went richer\leaner
-checked\relocated engine grounds
-checked and moved nitrous grounds
-swapped bottles and line
-made kit a dry system
-swapped MAF
-swapped nitrous nozzle
-played with nitrous jetting
-played with timing(low and high)
-different bellows
-added a little 103 race gas
-check all wiring and misc electrical
-bypassed MSD window switch
-gezz a few other thing I can't remember right now.
but to no avail. He thinks it might be something internal or a head gasket. The more spray he gave it, the worse it got. The 100hp graph looks like someone spazzed out while trying to draw an arch, its really weird looking. The nitrous just comes in and goes out. Anyone got any ideas?

What's the afr look like on the wide band. If it is too rich it will surge. Should be 11.8-12.0 range. They should have pulled a plug on the dyno after the issue to see how it is running. Make sure plugs are good and distbutor cables are tight. Make sure the n2o line doesn't have any axtreme bends. Check the solinoids for blockage like teflon tape. Just some ideas.

I'm guessing stock injectors? Ok what is the fuel pressure at the rails and how far does it drop when the N20 hits? I'm not familiar with that cam what are the specs, specifically the LSA?

Has stock 28.8lb injectors and an in-tank 255 pump. Dunno what the fuel pressure was on motor or on the bottle ( i wasnt there when he tuned it so i dunno any of the specfics) but i'll see if Allan remembers. The cam is a 232/234 .598/.598 on a 112lsa
Think my tranny is starting to slip, could that be the cause? Its been rebuilt but it was over a year ago

Could be but I don't think so, he said it runs good on motor, if it were the 02s it would run erratic on motor as well as on the juice.
