I would be interested to know what chips you have tried?
I have used ecu chips in Auckland and superchips nz both gave very good results

Have tried dp adjustable chip and think the other 1 was a tdc chip, truck struggles to do over 100km and has no torque

A couple of weekends ago I worked on a mates 2005 RA Rodeo with 4JH1 that was also sluggish. He had fitted a chip but was not seeing a huge improvement.
It had a broken bolt in the exhaust manifold for the EGR so drilled that out and put two studs in instead and placed a blanking plate at the EGR as well.(later had to drill a 5mm hole in it due to check engine light coming on) Reset the valve rocker clearances as they were tight. Found the viscous fan hub was faulty so removed it until the new one comes in ( this was causing a huge lag on the engine). We carried out an engine oil flush with CEM products and did an oil & filter change.
He said it showed a much better response on the trip home. Quite often just fitting a chip is not going to make that much of a difference due to other things requiring attention first.

im a mechanic haven't just fitted chip, have removed cat, fitted big exhaust, removed egr, tried 3 different airflow meters, swapped injectors, has had good service history, it doesn't smoke at all needs more fuel, have another ra rodeo 2wd with a modified vp44 pump and no chip and it hauls
