My brother in law has a 2001 diesel 3ltr hilux (non turbo) extra cab. This machine is an absolute slug on anything resembling a slope on-road. I mean, crawling in second uphill while road trains overtake on the fly. Is there any information or ideas about what can be done to this vehicle? Has this been seen before on this model?

Anything appreciated with thanks.

Yes that's par for the course I think Boxa. I was passed by one on the Hume Highway at 100kph. I was towing a 17ft van and on cruise control in a Prado. Next rise I found myself catching and then passing him. I maintained 100 while he must have dropped to 80kph. It's just the lack of turbo of course and it's probably OK off road. Even the 6cyl normally aspirated diesel in the standard cruiser doesn't produce as much torque as the TD Prado (3l 4cyl). See Toyota site for figures if you are interested.

Leroy ... No, I am not on the trader list on this site. That is why I didn't say who I was. Whether I sell this person something or not, it is not my major concern at the moment. But, if I can provide him with something that will help his problem, then I have done something good. By giving him a sample, if it doesn't work, then he has lost nothing. If it does, problem solved. If this person doesn't live anywhere around Melbourne, then I can at least let him know where he can find this product, in which case, I will not make one cent out of it. Thank you for taking the time to read my response. Tuddy.

I run a Triton piddly little 2.5 turbo diesel with manufacturers rated 62kw motor, less than a Mits. Mirage & 200nm torque @ 2000rpm . It will climb long highway hills in 5th at 100-110 kmh at about 3000rpm, & makes 135kmh plus on a good day.and about 10kmlitre at 100k,s
What rpm is the Rolux running at? This will affect the grunt particularly if it has the same diffs as the TD versions with electronics.
Wide tyres WILL reduce the performance and increase fuel consumption noticeably.
A dirty air cleaner will do the same.
Diesels take a while to free up & give their best.
Have your pump timing checked, preferably on a dyno. I am told many come out of the crate with retarded timing. My Triton was advanced a bit with benefits.
I have heard the 3.0 is a bit slow by modern standards but I am sure it will be less trouble in the long term without all the mystery gizmos.
Maybe a free flow exhaust will help allround too & dont forget to release the handbrake! Sorry, kidding.......Ian
