I have tested some of the files, HP and torque were there,
but they all had problems with over boost protection.
Managed all that often trigger it with a boost spike
(maybe my driving
), fuel is switched off and it feels like
you have to collide with something, and a really dull thing
is that ECU seems to set a "dangerous" flag on the trottle position
where the spike arose and this flag is not reset until the engine
has been switched off, this means that you can not use the entire
trottle register without the boost protection triggers even if
you are not under boost.
(lots of kangaroo'ing befor engin have bin switched off)
After one week I was realy tired of those chips and did go back to OE.
The most sensible is probably using a known chip such as Squadras or to use the Dawes Device to increase the charging pressure when the OE chip seems to be flexible enough to handle a higher base boost.
Also if you run a chip of more or less unknown origin, you should use a wideband lamda so you can keep an eye on that the engine not runs lean, with burned valves and similar as results.
