TA23,

Mate I don't know who is Tuning your car for $250 but that is VERY cheap. I asume they are doing it on a Dyno and have some idea about what they are doing ??

Going rates for Dyno time are around $110/hour. I cannot see anyone going right thru your cars mapping in just 2 hours, Also given the program will be being changed to Map sensored the ENTIRE mapping will need to be redone. Not to mention ensureing it is all connected properly and is actually safe to Dyno. (Any decent workshop will pre-dyno your car prior to it seeing the rollers.)

Sounds like you either have a real bargain or are perhaps getting some suspect quality tuning.

Running a turbo car out of tune is a pretty bad idea. The 3TGTE is not very forgiving so unless your looking for an excuse to rebuild it I would at least make sure it is running at a safe level. Keep in mind if its running to rich it will not only foul the plugs but if its overfuelling to heavily it will thin your oil with the excess fuel that runs down the bores.

And don't think its its rich it won't ping, to much timing is to much timing regardless of how much fuel its getting.

Hope that helps.

I am getting a fair bit of work done there at a later date, he said something about mapping every second cluster (forget the words he used) so it will not be a perfect tune, but enough to get it running MAP sensor and running a hell of a lot better than it is, it will be done on a dyno and a before and after readout will be given to me.

Would my oil always being black explain that it is over fueling, even after an oil change my oil still seems to be fairly black?

If this is converted to MAP sensor do you think I will use alot less fuel and gain some power?

Thanks for your help.
