i have G35 COUPE 2003 AUTO ,,, (( air-intake + spacer 5/16 + crank pulley + buddyclub consider )) 2 days ago i put JDM headers with the testpipes ,, it was good but not very very good as everybody told me a bout the headers ,, so what is wrong ??

is it the ECU ???? or what ???

 

what ??!@#$%^&*&^%

 

you make no sense...

 

Uhh ya, reset your ecu.

 

No comprendo!

 

So did you not get the performance gain you thought you would??

 

hey kuwait_g35 - do u live in kuwait?

im in dubai - drop me a pm. i can prob help you out

 

tune

 

stock JDM headers? or an after market JDM headers?

 

it is after market JDM headers ,,, and yse i did not get the performance gain as i expect ????

 

Tune, ECU Reflash, UTEC...which ever one you do will be fine.

.

.

 

Well, what is the difference between "good" and "very very good" on a butt dyno?

 

i think you're expecting too much

 

maybe i will get the reflash .. yestrday a stock Z race me and kill me in the
4th

 

headers are worthless mods.. it's always a hit or miss for the g and z.. it's easy to have it not sit properly and leak. if you're not gaining any power, wait a few weeks for your ecu to adjust and see what happens.
