We offer telephone support.

Our tuning boxes also do not have to be TUV approved like many competitor units manufactured in Germany, resulting in a significant cost saving which can be passed on to you, the customer.

Every unit is individually tested to tight specifications.  We test units on a wide variety of vehicles and have developed and rigorously tested every unit we sell for the application it was designed for.

Our tuning boxes are designed to give smooth, useable power increases.They don’t cause the car to pour smoke, go into limp home mode, or overstress the engine to the point at which you risk damaging components. The default map provided on our tuning boxes increases torque without increasing maximum fuel pressure, protecting your fuel system from additional wear.

We provide detailed fitting instructions for every application we sell a product for: When comparing us with our competitors ask yourself this: If they claim to have tested their system on a variety of cars, why have they installation instructions for only a few vehicles? We promise you that dyno testing is much harder work than taking a few photos…

All of our products carry a 28 day money back guarantee, so you can purchase with confidence knowing that if our products do not perform to your liking, then you can send them straight back for a full refund.

You may ask why our products are so reasonably priced? The real question should be why are the other options so expensive?

Kia sportage my 18

Steve is great. Was very skeptical at first. After reassurance and a 28 day return policy. So I bought it. Had the chip in the Sportage for a year. Great performance over stock. A lot smoother to drive and makes it more to drive especially on open roads

Amazing

I purchased the s SW chip for my new 200 series as I found the car in original tune was sluggish,the gear box was continually hunting and when towing the engine could not get into top gear. The so called king off the road was a real letdown by comparison to my previous tow vehicle a discovery 4 HSE.

Steve at SW diesel confirmed my issues and promised a marked improvement.

Well as soon as the cruiser with the chip hit the open road it was apparent just what a difference it made .The car responded better had more power ,got into top gear more quickly and held it and generally became more drivable.

Next for the towing comparison, well it’s a different car!

Finally I’m getting performance I expected from a 4.5 litre turbo diesel

The gear box doesn’t hunt as often ,the power delivery comes in more quickly and it’s a far more relaxing experience.

I might add that that’s towing a 3.2 tonne full size off road van.

Thanks for changing my whole landcruiser experience for the better.

Cheers Tim

Smooth & Responsive

My Porsche Cayenne was frustrating to drive in traffic with turbo lag down low and a not so responsive accelerator pedal nearly getting me rear ended when pulling into traffic. After speaking to a friend who has an SW chip on his car and after contacting Steve who listened to me and reassured me the SW was what I needed, I got it and installed it. Now the car is so responsive and power delivery so smooth with no hesitation at all. Definitely worth the money!

200 Series Landcruiser (2012)

Before trading in my 2011 Ti Pathfinder 3.0L V6 Diesel, I took out and sent back the SW Diesel Chip for re-tuning to suit my 200 Series Landcruiser. The Chip was back with me in under a week! I had Steve put a 2 minute pre-start setting on as well.

The Landcruiser moves through the gears (up and down) a lot smoother and have noticed that it kicks into Overdrive (6th gear) when it should do now instead of waiting for God to tell it!

I have hooked up the caravan and you wouldn't think it is on!

In sum, the Chip has exceeded all expectations and it is a real comfort knowing that Steve is only a phone call away if there any problems.

Better than new

Self installed on a VDJ79 that had 300k on the clock. It’s like a new car now, possibly better than the day it rolled off the factory. Photo instructions pointed to one of the EGR sensors - don’t plug it into that! The fuel rail sensor is at the back of the rail and you need to take off the intercooler to get at it. It’s about a ten minute exercise but well worth it. I’m going to move the intercooler to allow easier access to the plumbing and wiring. Silly design by Toyota.

Navara NP 300

I have a Caravan Hire business and deliver vans all around the the big state of WA and Having had a Navara D40 for 12 yrs doing the job with nearly 400000 klm on the clock without a problem apart from a Timing chain upgrade it wasn't a hard decision to upgrade to a Navara NP 300 bi turbo model this year. After 6 months I found the torque towing up hills etc did not match or exceed the D40 ,thou I had modified the D40 with chip, 3" exhaust and a few other engine upgrades for the job. So on looking around for a new chip and discovering the manufactures of the D40 chip were now charging around $1500 and it only altered the Fuel pressure I did some research on the internet and came across the SW chip which also controlled the boost pressure and a much more reasonable price.

Had a neighbor from up the road who also had a NP300 who told me his experience of fitting a Italian made diesel chip that only increased common rail pressure and he said it created so much pressure even on the lowest setting ,it was the injectors hammering noise was like a machine gun firing under acceleration. To which he quickly removed and threw away, he said it only cost less than $200 so I guess he got what he paid for. Any way purchasing locally and having a contact to ring if there was similar problem was one of the reasons for buying the SW chip. Having now had the SW chip (on standard setting supplied) fitted for a few weeks I very happy to say it has improved the towing ability of the Navara a good deal, It is torque that matters and it holds a higher gear in the 7 speed auto without hunting around like it used to, were it got to stage I use to use the auto like a manual, to stop the hunting. I only now have to slip it back to 5th for the larger hills and vans. Belting into a head or strong side wind that we often get hear on the west coast is not the same hard slog it use to be and have noticed a decrease in fuel used especially when towing so that alone will pay for the SW chip . Also have not experienced any increase in Injector Rattle, if anything quieter than before , Well done SW diesel.

200 Series Landcruiser

Well I was looking at a remap after getting the exhaust done and then came across these guys at Bathurst. I purchased the unit and we installed it with ease in under an hour and my god what a difference.

The increase in power was unbelievable and there is no lag in the turbos anymore and fuel consumption has come down but power is up ? Unreal product and glad i found them 🙂
