Tuning options - Puma

Reviving an old thread here, but i am looking into to this myself, looking at buying a puma but i am not sold on the power, its impressive enough compared to my 1kz-te prado, but thats no rocket either. If i get one it needs plenty of grunt across the rev range mainly for towing the camper on the beach, after driving one it feels pretty dead off the mark but then comes to life as the revs pick up, i guess its a bit of turbo lag but it seems quite possible that its made worse by the fly by wire lag.

After driving Dullbirds 110 on the beach you really notice the gap between 1st and 2nd in the soft stuff because of this low down lag, anyone with a chip out there notice an improvement in this area at all?

Also are there any puma 130 owners around newcastle willing to come for a play on the beach with me sometime? i really want to know this motor/gearbox setup before i comit to spending 55k+ on a very basic ute.

Mick just so you know I have noticed that the car is a bit laggy fullstop I'm considering putting some metal or silcone pipe on the intercooler and turbo lines I'm thinking that this may help...

my car never used to be laggy at all and I have noticed that it just doesn't seem to pull up hills like it used to so going to check this avenue first. If I were you I would see if you could get another drive of a puma on the sand as it simply could be that mine isn't feeling 100%

Has anyone tried the DP Chip? Developed by Berrima Diesel. They seem to know what they're doing. If you have tried one in a Puma, how did it go?

The DP Chip power gains promises 90 kW to 107kW. I have no idea about the BAS power gain but BAS promises to turn off the EGR electronically.

i'm keen to hear if anyone is running the Bluefin by Superchips UK they claim 40Hp and 102 Nm extra. ECU upgrade similar to BAS but only AU$535

Just to confirm Dulldird's comments, turbo lag isn't an issue on my Puma - it's much better than a number of other turbo diesels I've driven.

For example, as long as the revs are above 1500 it'll pull 3rd beautifully. Certainly no dramas when driving on the beach either - though I admit to not having towed on sand.

To be clear though, I'n not saying the Puma is a powerhouse (and I'm watching this thread with interest).

I've read recently on the defender2 forum that you can pay for a code to tell the computer to close the EGR valve permanently. No more need for a blanking plate, and no more light appearing on the dash showing a fault. :eek:

The chips sold by Devon 4x4 in the UK seems to be a half decent option. They are not cheap, but the old saying of you getting what you pay for...

These guys are Land Rover people driving Land Rovers in competitions like the Malaysian Rain Forest Challenge and the Outback Challenge. Maybe I'm too gullible, but when guys like these recommend gear they'll use themselves, I do take note.

Performance Upgrades

Most things in their shop will be delivered in Oz within 4 days. Again, I have no affiliation with the business, just reporting on very good experience dealing with them and the power of the Aussie dollar makes exchange rates very attractive.

With regards to the lag i noticed, it was also noticable on the new one i drove. Its more likely a throttle lag thing more then turbo lag, which isnt much fun for soft sand driving. Overall general sand driving would likely be a breeze for the puma, but when it comes to a nasty bit that requires a bit of throttle control is where i noticed that Lou's defender was hard to work out, given some more time driving one on the sand i would probobly get used to it.... i hope.

The lack of grunt is also very noticable on the 1st to 2nd gear change in high on soft sand, does anyone know the specs for gearing in the puma? what transfer is used? i looks like a LT230 but i only had a quick look.

Think of First and Second as 1a and 1b :D

The transmission ratios are

First 5.441
Second 2.840
Third 1.721
Fourth 1.223
Fifth 1.000
Sixth 0.742
Reverse 4.935

The Transfer Case is a LT230QRS and its ratios are

High 1.211:1
Low 3.269:1

At 2000rpm, I am doing 100kmh. But then, I live at sea level, so that helps :)
