GQ RD2.8T injecter pump enquiry

[reactbob]

Hi I have a GQ with a 2.8T engine and I have a problem with EGT going well over 550 degrees. I have had it to a dyne tuner to adjust it to get the temps down. but it is no different I think it is getting too much fuel and I would like to try and turn it down but do not know how to do this. I dont want to break anything so any help would be appreciated.

Regards Bob

When is it going over 550? Seen plenty of trucks including mine hit 600 pushing highway speeds up a long steep hill.

If its only brief periods and the temp drops back ot normal quickly I've been told not to worry about it.

Thanks for the reply lachiek if I have a bit of a load on the car I cannot keep it at 110 on the freeway every time you push the accelerater down a couple of millimetres the temp goes straight up. I don't knew what else to do.

Regards Bob
