  1. I have a DP chip in my Prado D4D (2008)Auto. For around 4 years and around 80K+. It has done it's job well. I tow a 20' van and it is definitely an improvement. In standard trim I feel that the prado is a little sluggish at lower RPM, and in my opinion thats where the chip helps the most. I don't work my Prado very hard and the chip does its job well. I also run UNI Filter and a larger exhaust(beaudesert). I had mine tuned up by turbo Engineering in Melbourne and ray informed me that the DP chip increases injection PSI to gain the increase in performance. He did tweak it a tad(probably thru one of the settings). He did say the changes that the DP made appeared to not adversely affect the engine. He did say that injecting at 30,000psi is a bit of an unknown. He told me all the euro diesels inject at around that pressure.
  2. Hi fellow Prado owners, I have a 2008 D4D Prado that has been sensational to date. My problem is that I have been reading a lot about injector issues. Having been a owner of a 1999 Common rail Jackaroo for a number of years and having the misfortune of having had a fatal engine problem at 130K and the NEW replacement engine showing the exact same symptoms at around 100K, I decided to invest in a Toyota Prado. I trusted that toyota could build a great, Long life Diesel, common rail engine. However, of late, I have been reading a number of articles regards the issues stemming from the injectors. What I have not found is a solution!. I wonder if Toyota have done anything to address the articles written. Do they acknowledge the problem? Do they have a solution? How do I find out what the CORRECT solution is? By the way, great website guys, many thanks. Peter
