I don't remember... I thought it was 3...? I may be wrong tho'...
No... Everything is fine except that I didn't put the TPMS in the new wheels... I'll be doing it the next time I change my tires...which is like... uh... one and a half year later? lol

double yellow lights on the dash FTW! lol
hey its four. looks just like my sentra's 2nd o2. two whites, one black, and one light gray. sweetness, now i just need to hear this exhaust with resonated test pipes. if its good, i will source another o2 simulator.
the 350z guys with the HR are making impressive power with the intimidator exhaust and test pipes. along the lines of 15whp. cars putting down in between 275-283whp with that and intakes.

maybe 290-295 with the flash. i dont think there is any room for gains in the headers since we already have tubular 3-1 headers. 300 dead on maybe with some sort of a better designed headers setup.
300+ would probably only come with cams of some sort and a kick **** tune. look to nismo or various other japanese companies to see if they develop any for the 07+ 350z. be warned you get into the cams and your powerband greatly shifts to the upper rpm. makes the lower daily driven part feel flat. the stock cams may already be close to the limit for the motor. with the variable cam timing all over them, they can run aggressive setups and have absolutely no hiccups in the power band if they wish. i wonder what our factory cam specs are.
i experienced it first hand in my sentra specv when it was all motor fully bolted on. but once in and over the mid range it FLIES! I/H/E/test pipe/pulley/cams/safc2 tune/balance shafts removed/knock sensor desensitized/hypergounds had me almost 50hp over stock. 180whp then the 75 shot added a nice kick. 245whp 290wtq in a 2700lb car
that was before i went turbo ~310whp

Since Terry posted a mean gain of 8.3 HP and 5.5 ft-lbs, I am hoping to hit double digits for both with the exhaust and HFCs installed

I'm hoping for it to hit 15hp and 10tq!

Ok... have a little bit of problem here...
Almost 500 miles after the installatin of the exhaust+hfc, I just got the CEL turned on. I don't know if this is going to be permanent so I'm going to unplug the battery for the night.
I'll post up the result tomorrow. *crossing fingers*
Wish me luck.

Update:
I have put the battey back on and well... what do you know? The CEL went away. I'm assuming that it has to do with something from ECU. Maybe I was driving too carefully? I'm not sure, but I will try to drive real hard for the next 500 miles to see if there will be any differences.
Oh and another news. Terry and I just finished taping the vids this morning, and they should be up by the end of the day by Terry. I'd also like to thank Terry for his time and for giving me the opportunity to compare mine with his.
