Dyno results...Need some opinion !!
Hey guys, my car is a 2004 350Z, 6MT, track package.
I just finished from installing some bolt-ons so I thought I share my results with you.
My current mods are : Motordyne 5/16 spacer, DC headers, Megan racing test pipes, HKS replica cat back, BC 264 cams, Uprev tune, Exedy stage 1 clutch, Nismo suspension and Nismo body dampers.
This is my baseline, completely stock. All dyno runs were made in 4th gear.
Bank 1 intake cam solenoid valve was broken. mods: spacer, test pipes, exhaust, cams, uprev.
This dyno is after installing all mods listed above. Torque increased quite a bit. however, what is the reason for that dip below 3500 and is there anything that can be done to improve it ?? could it be a leakage of some sort? All feedback are appreciated
Thanks

I asked the guy at the dyno to send me the AFR figures and this is what he sent me...I believe this answers my questions...It seems that the engine is running a bit rich where that dip is but correct me if I am wrong.
Below is the AFR on the second run (310.9 Hp)
and third run (311.3 Hp)

i would agree, it seems your fuel map does have a hole in it around 3750, there is certainly no reason to be running 12.75 at that RPM. do you have an uprev cable? if so i can take a look at your fuel and timing maps

AFR should definitely be smoother through that range. Either it wasn't smoothed properly or your tuner added fuel to combat detonation(unlikely). 13.5 AFR may be a bit too lean at 4250 although not unacceptable. Great gains though.
