AFRS around stoich (14.7) or Lambda 1 are common in stock/mild turbo cars - they will run richer if component protection is required. Mapping will include running more boost and this is a useful article on fuelling - fundamental stuff. Not sure how experienced you are with this so forgive me if it's patronising.

Good job mate. This article is the answer to my question.
I specialize in LPG installation so there was no problem with understanding this article, very useful.
Most of the cars i met run with lambda a lot less than 0.9 (0.8 or even 0.7) so what i've experianced with 2.4T (LPT) whas not what i was expecting.
When i tune LPG conversion i always do it to the same lambda or AFR as on the petrol.
When i unpluged MAF, AFR droped down to even 10.8 so it was the reason of component protection.
You've done a really god job mate, many thanks.
Got the confirmation from HLM Hamish and they run with lambda 0.9-1
and booked in for tuning this saturday.
Interested whats gonna look like after tuning????
Cant wait.
Enjoy mate let us know how you get on.

Yeah, i will say.
Very very interested how is it gonna perform on lpg.
At the moment i cant feel any differance between petrol and lpg.
Hi everyone.
Some new boost been achieved on my 2.4T and from standard 1.31bar reached max 1.72bar.
Running full boost and max 6200rpm on lpg without noticeable power difference.
Very satisfied from car performance and HLM service.

a nice 50 whp there mate and alot more talk but i think the boost levels you are talking about are abit conserative lol
That"s with standard air induction.
Maybe could achieve slightly better result with custom cold air induction?
What do u reckon?
MAP befor 1.31bar, after 1.72bar
Everyone knows what does LPT can do.
Nice result, but suggest you edit your post above to remove a reference to the speed you were doing on a particular public road.
