The custom CAI i have isn't for everyone because it needs to be tuned with Uprev/Cobb.

who cares man,

all of us are tunning our cars nowdays.

Update !!!

I just got back from the Dyno
Let me tell you guys getting over 300rwhp on that dyno ( low reader) did not happen !!
I discovered just before I had some bad winter gas
it explain pretty much what we have seen previously and today !
nothing can be done about the very top end of the power band , no matter what the ECU pull a lot of timing even in the mid-range

result = 299.5 rwhp !!

previously on the car
280 rwhp
My DIY 350zHR intake manifold (M370 from Motordyne)
Stillen Headers
Test Pipe
X-pipe (60mm)
2x big resonator
Custom straight flow muffler
Light weight Crank pulley

----------------------------------------------
I still have some tuning to be done on the MAF table in Uprev
then some to get the proper fueling everywhere in the powerband
the next Dyno session will be sometime in April / May

with a little bit of tuning and getting the WOT pull relatively OK
we managed to test both new mods on the car
which is the Custom CAI w/ Oversize MAF tube
and then with the Oversize Throttle body

The new CAI provided 11-14 rwhp
the oversize Throttle body with the CAI 7-9rwhp
we barely did any tuning with the last mods (TB)
so the graph isnt so appealing but Im not worry about this because it was running leaner with the oversize TB on

that 20whp bump at the top of the rev range looks promising let's hope u see those type of gains throughout the rpm range! good luck with your project.
