Cheap tuning chip, may mean cheap development. I would stick with the 3 or 4 major players.
Engines cost a lot to repair....much more than the saving on the purchase price.

Have one fitted to my 3lt BT50.

I noticed a power increase, less throttle and more responsive.

Also noticed better fuel consumption, average about 10L/100km around town. Thats with larger tyres, steel wheels and a heavy right foot.

I have mine set at 8, i think it has 10 settings or so, it comes set at 7 which i kept it at for a while. They are a one size fits all chip, being that only the plugs on them are different. They only alter fuel rail pressure.

On highest setting the vehicle will shut down if it senses a higher pressure then it can handle. It cant do any damage.

Best $150 i have spent. No way can i justify spending $1000+ on a chip unless i was towing something really heavy around Oz.

Hi Muntoo, how long have you had yours installed? Certainly seems like a reosanable price.

Muntoo has hit the nail on the head....it only increases rail pressure. Speak to any diesel mechanic about the effects of rail pressure increase only.....very expensive to fix when it lets go. The two fuel injection specialists in WA love chips that increase rail pressure....good for their business.

Been installed about 12 months now. About 17000kms.

No problems.

Fella on the 4wd action forum has tested it pretty thoroughly. EGT actually lower then without chip fitted.

They are fitted with a over pressure fuel cut out anyway. If fuel pressure in rail is too much it releases back to the tank and engine will go into limp mode, aswell as engine light coming on.

Not sure how about you, but overboosting is far more dangerous and costly then over pressure in fuel rail. Many chips cause overboost, you dont know unless you monitor boost levels though.

Im happy with mine. Only running it at the highest setting will cause overpressure, setting 8 is enough for me. Noticed a comfortable/enjoyable difference.

ALL chips will alter fuel pressure, so there is no difference IMO.

Any chip which makes the fuel rail pressure higher WILL be making the High pressure pump work harder so be aware of this, quite likely it will shorten the expected life of the HP pump.

Also, the higher pressure, usually more than 20,000psi is increased to make the injectors spray/atomize the injected fuel and make it mix even more thoroughly with the air/oxygen available to gain more power etc.
Unfortunately the injector is having to withstand far more pressure than it was designed to do for long life, so don't expect the injectors to last a long time as they are now hammering themselves to death cos of the extra pressure applied to their seating/sealing faces within the injector.

So many he says she says and so many misconceptions!

A chip that increases rail pressure is fine and will not make the pump fail any quicker then anything else.

If they made something that was running a 100% duty cycle the engineer in charge should start flipping burgers.

We have found chips that increase rail pressure will provide more low down torque and less up top end and the ones that increase injector duration offers less torque down low and more up high ....... I like more down low torque.

There are so many performance chip manufactures in the world I would stay with one of the larger ones...... at least they may offer support when things go pear shaped.

It's funny how if something goes wrong with something the finger always gets pointed to the most obvious thing..... and the most obvious thing doesn't always cause the problem.

Why is it with these diesel EXPERTS..... two say don't and two others say do...... maybe these two EXPERTS don't sell that chip.

We ran a DP chip on our old D4D Hilux for 5 years and did 100,000K with no issues..... knew of many Hilux D4D's with half as many K's that didn't have a chip and had fuel delivery issues.

MATTCAR.... again stay with a known brand name.

All chips do the same thing to a degree.... increase fuel supply one way or another.
