It is possible to overfuel it and put extra unwanted heat into the motor. Is it blowing heaps of smoke now.

When installing the Pyro where is the best place to put it? I would guess closer to the turbo on the exhaust outlet side but that would be just that... a guess.

Thinking of getting one for my turbo GQ as I've recently had a dyno tune up and whilst I got a 50% increase in rear wheel HP and a greater increase in torque, now the car is belching black smoke, using shitloads of diesel and running substantially hotter on the engine temp gauge (factory idiot gauge not capillary type). I watched the tune job and there was no sign of a temperature sensor at all ... they just used a exhaust gas analyser.

Cheers
Simo
