Outer Limits 4x4 Board

just wondering i have fitted a front mount intercooler to my 2003 3.0td hilux. after i have finshed all the piping an everything do i need to get it dynotuned or up the boost or anything or can i just drive it after ???

You might get a drop in boost pressure with the extra piping and resistance from the intercooler.

Buy a boost guage and a boost controller and you can tune it back to factory spec.
Plumb the gauge into the inlet manifold, please.
Install the controller between manifold and wastegate actuator.

I have an Autometer gauge and a TurboTech controller, both work well.

ah ok i have a boost gauge its on 11psi as standard so after the intercooler is all hooked up i just need to up the boost to compensate for the loss and i should be right ?

would you recommend or know about increasing the fuel or anything or isnt it worth it and just stick to the boost pressure

You don't have to change anything.

While the intercooler causes a little drop (friction of air through the plumbing and cores), the decrease in temperature it causes means your engine is still getting more air.

Your engine will now run cooler exhaust and a shade more efficient with the intercooler.
It is not necessary to adjust the boost or fuel, this is optional and is only done if you are in search of more power.

Just see whether you drop much boost after installing the cooler.

I wouldn't touch the fuel... if you want it tuned later get it done by a pro with an EGT.

yeah i am not game enough to play with that i already replaced the head from it overheating ($3000 later) so i defenitely dont wanna spend more money on repairs i ll connect it up and up the boost a bit to copmpensate for the loss in pressure and see how i go . any idea how much someone would charge to do the fuel and tune it properly just curious so i dont get ripped off . or know anyone iin brisbane, queensland you woluld recommend

I thought it was around the 300 dollar mark... dont quote me tho

mate take it to Chapmans dyno and tune... in Cooroy sunny coast, one of the best around under 300 to get dynoed and tested... most of the bigger comp spec rigs in SEQ are tuned or have been modified by them

Upping the boost is not necessary, nor would I recommend it.

In saying that, if less air is going into the motor, due to losses, pressure drops or whatever, the fuel/air mixture will then be too rich.
In a diesel, this then causes overheating issues.

The engine will receive more air.
The density increase from the cooling is far greater than the density loss from the pressure drop.
