Another is to tie down the vehicle harder for the first run than the last run. I lost 50hp by someone over tightening the straps on one tuning session. Had me perplexed for a while.

It's disappointing as I'm sure the improvements are there, there's just no need to show inflated figures, or to bring the results into question like this. Admittedly it can also be fudged by playing atmospheric temp, ambient temp, etc.

Anyhow, I'd dwell less on what the chart shows and use the seat of the bum to tell you the improvements.

After driving the vehicle for a couple days after the remap, all I can say is it feels like it has a different engine in it ( seat of the pants measurement ). Not only does it have more torque down low, but it feels even better than being in sport mode on a standard TDV6 when in normal mode on mine. Also the engine revs more "freely".

Was it worth the $1,525 for added engine improvement for "me" - definitely yes. Only mistake I made was mulling over it for more than 12 months before I went ahead and got the remap.

Awesome. Yes power/torque down low is the best outcome as that's where you spend most of your time. I wouldn't care if peak power didn't change but got 50% more torque between 1500-3500rpm.

DiscoJeffster, I was pleasantly surprised at the difference it made, and obviously I was quite sceptical waiting 12 months ( where I did a lot of research and spoke to different people and diesel tuners ). I admit I have overloaded my TDV6 with too many accessories ( bull bar, rock sliders, winch etc ) bring its in unladen weight ( but includes me and a full tank of diesel ) to 3,060kg. Thus the reason I was really seeking some more torque - just to help offset the extra weight - especially when 4WDing. I'm a very quiet boring driver on the road, so I'm hoping the real benefit will be off road.

Thank you for the feedback Brad & Garfield.

IMO Roo systems is way to expensive for what it is and 17% increase is very low. I'd get your money back and go to a different tuner, or if that level of gains is acceptable run a plug and play chip for a 3rd of the price

thatsthe sort of thing we'd like for ours, especially to eliminate the throttle lag when leaving the lights.. irritates the hell out of my wife. Cheers :)
