So as of the past week - 2 weeks my engine seems to be feeling kinda slow and I'm not sure why. The cooler temperatures usually help the AFR performance but whenever I hit the accelerator my car does go faster/gets louder but it doesn't 'take off' like it had done previously. Here's what it could be/ or think it could possibly be:

1. My intake filter is dirty and I need to clean it

2. I got bad gas for it - I filled it up at Chevron though and put 93 octane in it

3. I need an ECU reflash to maximize my parts because the current ECU settings are actually slowing my performance. I have the following performance parts installed : Mishimoto CF Short Ram intake, Varis CF Intake Duct, Helix Test Pipes, JIC Y-Pipe, JIC Spartan Bullet ST Single Exhaust. I was talking to the guy @ Osiris who specializes in Z ECU reflashes and he said even adding an intake can effect your performance - not a crazy amount but getting your ECU tuned specifically for your car always helps.


I'm thinking it's gonna be the 3rd one more than the 1st or 2nd, but all opinions would be greatly appreciated.

 

how would I clean the filter? since it's attached to the actual head of the piece

 

Did it not come with directions on how to clean it? I am sure you can detach the filter easily. Get a K & N filter recharge kit.

 

any thoughts on the ECU reflash?

 

bump for some help

 

Uprev's Osirus is a good ecu reflash...IMO. no down time on car, no mailing, just email.

+1 get the k&n recharge kit for intake and clean it out...should help.

sunoco gas, exxon/bp gas, or shell...three gas stations that id pump gas from...mainly bp in my area since its the cheapest....$2.03 93 octane
