Shauno heads to Ultimate Diesel Tuning to expose some pretty serious issues with unsafe diesel carpark tunes!

Car park or flash tunes can be fast, cheap and will make a difference to the way your 4WD drives, but here's why you shouldn't take the risk!

More power often means HIGH EGTs, more fuel and black soot, bad airtofuel ratios and a whole host of of potential big issues.

When you're getting your 4WD tuned, make sure you've got a professional making sure your intercooler piping, turbo, injectors and overall engine health is up to the task.

If you're chasing BIG power from your diesel 4WD, you'll need to consider reducing intake air temperatures by fitting a bigger intercooler, lowering exhaust gas temperatures with high flow exhaust systems, upgrading your injectors for more power and a whole lot more!
