Hi Lozza, I've had these mods on my 2001 Prado for the last 7 years and approximately 180,000 Klms, it's not so much what mods you do it's more to do with your right foot and how you drive it.
The bigger the exhaust the better with a turbo, the least amount of back pressure the quicker they build boost. To add a larger exhaust you remove the original cast dump pipe behind the turbo and replace it with a larger
bore one, you also replace the standard muffler with a straight through big
bore (3") one, approx $800.00 for exhaust.
Standard boost for a KZTE motor is 7 to 9Lb, engine light comes on at about 14Lb boost. A boost contoler allows you to dial up what amount of boost you want, in my case I often run to 19Lb boost, and when I purchased mine it was about $70.00.
The Tunit chip cost around $1,100.00 and was least power gain for the dollars spent.
My Prado has a little more power than a D4D Prado. Fuel ecconomy suffers, (11.7Ltr/100Klm), depending again on your right foot.
