Hey yall, I have a quick question and I'm hoping its an easy answer. iv had the ba flash tuned and few other things done, recently had the trans rebuilt. But now when I stick the boot into it the car backfires and sends a HUGE smoke screen out the rear, Do I just need a new tune? or is there something more evil going on?

Custom tuned or Generic? Does it still do it when running on stock tune?

I'd be taking it to a tuner for a service straight away I use Pit Lane in Frankston

Thanx bro il look em up, they nice and close for me.

Hi,

Most likley what the problem is will be the spark plugs. As the boost would have been set a couple more PSI the spark plugs need to be regapped from 1.1mm to 0.75mm or 0.8mm.

It happens on a few cars when you raise boost, Skylines do it also and they have to use a hotter or colder spark plug.

The tuning shops usually charge about $150 to regap the plugs but if you are handy you can do it yourself.

You get the same symptom if the Plugs are stuffed as well!
