Problem with my nav?

[Steedjo]

Hi there, i have an 04 str nav, and it seems rather gutless. Gutless enough that its comparable to a 1990 hilux. It has no mods, have checked the turbo its running at 15 psi. Any ideas? Also have changes the neutral position sensor as it was playing up and under load it would surge, but that fixed that problem. Apparently its a common thing at around 190 000 km's. Dont know if anyone has posted about this yet.

Check the Boost Sensor, also known as Map Sensor.
