Thinking about slapping a cheap eBay rail chip into your ute?
Think again.

It's not a "quick power hack"... it's a blown injector waiting to happen πŸ’₯

Not only do you get better results from a custom remap, but you also get much safer results.

⚠️ Please do not trust your ute to these chips; you'll regret it (and it won't be a cheap mistake).

Another 79 Series in for a custom ECU remap.

It left the shop with an extra 33.6 kW (+25%) & an extra 318 Nm of torque (+74%!).

The mid-range is where it really comes alive, with huge low-down torque that you'll feel every time you're towing, loaded up, or getting off the line.

Every tune is custom-dialled on the dyno for power you can actually use, safely.

Got a 79 Series that deserves the same? Get in touch. πŸ‘‡
