Well after two years i finally solved my stumbling and constant hesitation. I put on a new MAFS and cleaned or replaced everything that has to do with my EGR system. My small egr pipe was almost closed.
Well my350z.com was having a z meet in connecticut at xxtuning, i went to look at the z's and dyno my car. The z's were putting down around 235-240 stock and procharged 355-385.
I put down 197.1 fwhp @5700 and 192.44 fwt @4650 .

 

Nice numbers what are your mods? Just by looking at the numbers and if your 5spd I'd assume VI + intake, y pipe and exhaust or so.

 

REAL nice Numbers! wish i had known, i woulda gone... xx tuning is only 45 mins away from me

 

he's gotta have more than that to put down 197hp. ECU and something else included. Also isn't the torque number a bit low? Put this in the DYNO forum or ask them to move it. Also show your A/F graph...

 

My numbers are posted at my350z.com in the regional forums by vic.
I have greddy mufffer,cattman b-pipe,cattman y-pipe ,stillin intake ,frankincar midpipe,UUDP,and my 70mm pathfinder tb with ported out intake manifold.

 

dang, that is an extensive list. get ECU and mevi!

 

Thanks, im getting the ecu next. The guy doing the dyno said my hp stays good on top , its 175fwhp @6318 my car cut out at 6318 ? Torque is around 145.

 

wait...but you just said you put down "197.1 fwhp @5700 and 192.44 fwt @4650" so which set of numbers is right?

 

The other ones are when the cut off was not his peak...

 

oh, i got it now. that seems like a very large drop off though. mevi and ECU would help that cut off largely (obviously) raised rev limiter gets you a much higher cut off, and makes some power to counterbalance where the mevi falls short in the mid range. your peak and cut off would be higher...but you already have a lot of power
