might b a vacuum line gets some soap and water and put it over your rubber hoses in the engine bay some might b split.

and make sure intercooler pipes are secure.

maybe it's the famous flat spot generated by the stock r33 ecu?

car boosted at all?

u can try resetting the ecu, or do what i did go see a reputable tuner, if he is good he will fix it for you..

if u are in melb let me know, i know a good tuner that can help.

thanks for the help guys.Car is boosted at 12 psi.Other mods are a bov,3" turbo bak exhaust,dump pipe,filter.will resetting the ecu fix things and how would the ecu get so stuffed it'll cause these problems.And whats the flat spot.

Definately R33 ecu flat spot.

The ECU isn't 'stuffed', it's just not a particularly mod friendly computer.

An SAFC will improve performance but a PowerFC will give the best results.

try spark plugs if they have not been looked at in a while. I have the same power loss feeling in mine. New plugs and shes apples..

Worth considering if u have not already

ecu's retarding the timing?

or your trying to drive a pancake again?

This brings a question up what mods are ideal for the stock ECU before it goes all funny.

[Guest tkch55]

take the boost down to 10psi for now before you get the aftermarket computer, then it will be fine

[R33_Series2Lover]

does the boost make the ecu go all funny??

12psi is straight into rich and retard mode. I am most certian on this.

11psi is safe, and 12psi - ECU shits it pants.

I can almost guarantee that it will be overboosting a little too causing the rich and retard to work nce and hard for you.

Simple solution - Wind your boost back to 10psi, and make sure it doesn't spike over 11psi and you'll be fine.

Another solution is to get an aftermarket ECU. Thats what I did. Because With those mods and the factory ecu, my boost was spiking up to 14psi briefly... Going from 140rwkw to 110rwkw...

heh - powerfc gets me 210rwkw...All day every day...and safely
