Guys,

Got my car tuned today after having -9 turbos fit in on stock engine with power FC, exhaust and bleed valve....

was a bit disappointed by getting only 286kW.

It did 265kW before that....only 21kW difference after changing stock turbos to -9?

Does that figure sounds right?? just a bit curious....

Its on a GTR33, stock motor...

Help me guys, after spending that money, i was aiming for at least 300kW....

Do you think there is a problem or should i have supporting mods? If i need supporting mods, what minor mods can i have??

thanks guys :)

were those figures on the same dyno, same settings

The previous figures was on the same dyno as well....

I was thinking of getting an opinion for another tuner....

i was been told that if i had smaller wheels, i could get upto 300kW ???

Sounds right, for safe tune.

Changing timing to bit aggressive top end may get you 300rwkw. I did this after wanting 300rwkw and told tuner to make me happy so he did it.

EBC - Electronic Boost Controller. If you've got heavy duty Garrett or HKS actuators, EBC may not be required. You've also got bleed valve so was told it's fine.

I do have bleed valve, so i may not need EBC....i have the standard HKS actuators....

i was thinking of fuel pump and changing the injectors....

OR

get it fully retuned by someone else as well.......

At this point, I'd talk to few tuners and see what they say about your setup and your power goal, and go from there.

Changing fuel pump and injectors wouldn't yield more power BUT will give you extra fuel to feed into motor so you can raise the boost to achieve 300rwkw (I achieved 302rwkw at 90-96% injector duty - not recommended), you'll need Nismo AFM for better resolution (again, talk to tuner they should explain you better).
