Hi, I had a very strange issue yesterday.

My Airtrek Turbo usually boosts around 22psi but I took it out to work and it would only hit 15psi.

Checked the logs on the Evodroid and it was also showing knock as high as 8 (most of the knock had been previously tuned out) but it was running okay.

I thought that it could be bad fuel (it was filled up the evening before), boost leak, etc. but after leaving it all day in the car park it was fine - back to boosting 22psi and today it is fine.

Of course, the optimist in me was thinking that it was nothing (maybe just not plnating my foot firmly enough) but years of experience make me wonder if more is going on...

Anyone have any ideas?

Thanks in advance...

 

Was the temp hotter outside when you picked up knock? Have you got water/meth kit?

You're saying it's fine now?

 

No and no.

Yes it is fine now... Very strange.

 

Maybe a bad batch of fuel...
