I'd put the TDCO back up to -1.94.
Bosch India suck, I posted pics of low mileage ones.
I'd say change out injectors with known good ones.
Also, make sure the exhaust isn't touching the body or frame, that the engine and transmission mounts are good and not broken or collasped.
I just did...
Looks great.
Are you using tygon for the return line? If so, its not that good, its overhyped. :( Mine got very hard after a few months and started to leak. I see you have zip ties on but for the price of tygon, you can get a decent return line that doesn't need clamps.
Lol, they were $400, the electronic is $475, I called Jan or Feb and he had plenty, I guess me asking around has people buying them, :mad::( Let me sleep on it, I"ll get back to you tomorrow, :cool:
I used a die grinder like above with the large fluted bit for cutting aluminum, cuts plastic without plugging up. Just be warned, you can get carried away, lol.
Certain year Dmax's had cooling issues.
They don't run water cooling on regular Holsets and when have you heard of a Holset Cummins failure? I know they use water cooling to prevent coking but they probably put it on the VGT due to the extra heat produced. :wacky:
