Exactly but back to Lortaps post you still have excess boost were does it go??? As the name states out through the turbo and exhaust. The variable vanes fold back release boost and walla! Job done. You might see a spike in pressure but no more than the Fast and Furious dump valve noise. Both methods are a plus.2016 ISUZU DMAX TWIN CAB.

Hi lortap, reading from a chip tuner website that I got through some one on this forum, when a remap is done they disable the EGR (close it during boost, but open it off boost) so no faults are recorded, and so long as the remap is reliable, and Dabeanian's seems good, I am thinking of going down that route also. All the usual safeguards for the engine are kept. Phil

In a other land far far away I think it was South America a Prado Pointer joined this thread inquiring as to where the EGR valve was. After posting some pics there was none not even a heat exchanger that could possibly fail. Turns out South America are slack with emission controls. I cant find the thread but it would be good if we could contact him again and get some pics of the type of turbo they run there.2016 ISUZU DMAX TWIN CAB.

i had an interesting talk with a great mate that tunes race cars in QLD ( i know quite a few guys travel BIG Km's to have him tune their race cars !)
he has been doing the race cars for 20+ yrs
6mths ago he got into doing the road cars with the diesel engines
most cars are done with just a program that is supplied
(to do the tuning on the car specifically to suit that individual car a special machine is required at a cost of $100k, which there is only 2 of at the moment)
he is working with the guys that have the machine
he does the run on the dyno with the car then goes through the parameters sends the file off with the changes required and then recives the file back loads it back in and does another run
this continues till he has the engine running the way he likes it, on most is is 5 to 7 runs on the dyno, not just the quick flash load that a lot do
don't get me wrong they are all good tunes that have been done on someone else's car at some time
so i guess i will be taking a drive to QLD soon to get mine sorted out2008 Dune D4D manual GXL update - with lots of fruit !! + Roma Razorback Off Road Van

G'Day. I'm a rookie here, and not sure if this is the correct place for this comment, but here goes anyway. I have a 2003 Prado KZJ120R TurboDiesel (purchased second hand last year 180k Km ). I require more grunt and better economy (getting a constant 13l/100km open road, not towing) , so put on a 3in exhaust and an Ozbush manual mapper. Fuel consumption dropped by 0.4 l/100 on the open road with Ozbush mapper set at -10. I then had a dyno test to find 63 Kw at wheels Ozbush off, and 65Kw with Ozbush mapper on best setting of +7. So pulled Ozbush off and returned it and got half my money back. I'm still looking for better economy and more grunt. I have been told this motor cannot be remapped at all, but can only be chipped. I really don't want to spend $1200 to $1600, and I can't find a second hand one! What are my options? Any ideas, please?
