Dyno'd missing 25hp help me find it!!!
I left my silencer in like a dummy so that was about 10hp. mods are
JWT ECU programmed for the following
8:5:1 W10 motor
BC stage 2 cams
T25 370cc
Z32 Maf
Nismo FPR
Stock timing
2.5 in downpipe, 3" exhaust (no cat)
7psi



I was hoping to hit at least 200hp with my setup and feedback is helpful thanks...

you need to take some fuel out. your running rich. I would get a safc2 and retune.

agreed on the rich side plus that silencer could def be restricting your power level did you tune with more boost or same boost just altering the fuel map

Im right there with ya JT.

How about we both just say that the dyno was reading way off? Seems like a typical internet excuse. And we can prolly pull it off cause we dynoed the same day at the same place.

I think i have timing issues. After 4500 the line is all over the place. Not very smooth at all. Im told this is caused by timing.

No tune, this is a base dyno just to see where I'm at before tuning and turning the boost up.

I forgot to put in the mods list I have BC stage 2 cams and only the downpipe is 2inches.

Thanks for the feeback, I have an SAFC2 not hooked up and a wideband on the way and I'm gonna advance the timing to 15 deg. Should I get a 3inch downpipe as well? I been looking for one on but it's usually for a BB setup.

3 inch downpipe is really going to help you all the way aroudn the pipe you have now is probably really restricting you a larger downpipe is really going to open up the power

They just come and go so fast and a one from JGY is kinda expensive...
