Mods to do before putting in ECU and tuning...

[Milgram]

Hi all,

 

Can some expert(s) list down the GENUINE mods (those that REALLY increase performance) we need to do before putting in a piggyback ECU and tuning please?

 

So far, this is what I have been told works:

 

(1) Change to a good performance exhaust system

(2) Change to a lightened flywheel & clutch system

(3) Change to a lightened crank pulley

 

Anything else to add to the list?

 

I was told that the following things that people commonly do, does nothing substantial for performance:

 

(A) Cold air intake

(B) Air charger

© Grounding

 

Anything else to add to this list?

 

Thanks!

Change intake system to open-pod? Decat?

[Sickscientist]

Dont bother with all these enhancements... Concentrate on IPO..

Thanks to bro Darklord for this input. So you sure it works? I add to the list first. Additions in RED.

 

(1) Change to a good performance exhaust system

(2) Change to a lightened flywheel & clutch system

(3) Change to a lightened crank pulley

(4) Change to open pod air intake

(5) Decat

So you got get the China Oil shares bo?

If you're doing re-tuning, might as well get those open pod with CAI, which has a larger than stock diameter inlet tube.

 

Install manifold spacers/insulators for cooler air intake.

 

Install bigger fuel pump / fuel pressure regulator.

Intake---Close pod/open pod. Increase in piping diameter.Throttle Body also...

Header---4-1/4-2-1 (depending on ur requirement)

Exhaust---You know what's this and what to do with it

 

The most basics but the most hard to find complement with each other.

Got to play around with individual combination.

There will be a difference! But performance would be naturally be further enhanced with other mods - most significant I believe with a conversion to an open-pod air intake system.
