Thread: Td5 Boost Pressure

Paul you could be right maybe I should try without the Snorkel.
I would doubt if I got 2 from a bad batch 12 Months apart though

Even so, and factoring in that you see 522 peak, a peak reading of 420 maximum is what I'd call "a bit low" - by 20% compared with your figure. A Siemens/VDO MAF in good condition is definitely a good reference for what a Defender Td5 should be reading.

I meant Xtreme should check this. His mate isn't seeing any more than 1 bar/14psi boost, so it's worthwhile checking.
