ok....so N249 replaced and boost gauge moved to the dv hose and now not getting a vacuum reading getting a boost reading so all good so far. had a bit of a drive and acceleration feels a lot better and seemed to peak at around 18-20psi instead of 11-15psi. Was all town driving though so will need to take it out on dual carriageway tomorrow for some more testing but was still some turbo hesitation, most noticably in 2nd gear from 2-2.5k and 4.5-5k rpm

Took it out for a run and with stock DV there was no apparent hesitation and these were my logs. Is it bad the actual is higher than the specified even though its not by a lot?

The place I was going to take it to on Weds and now saying the KO3S will need mapping in, but to do that I will need to buy bigger injectors as the logs show these are already on their limits...is this correct?

I maybe wrong here but....Something tells me that tuning company is bad or has things confused by what you just posted.
Ko3 and the so called ko3"s" doesn't need an injector upgrade.
From a ko3 to a ko4-23 yes it's needed along with a few other bits.
From a ko3 to a hybrid ko3 yes, again it's needed along with other bits.

I don't understand the logs which is why i posted them here, but from those logs posted they are saying that the injectors are already being pushed? what graph/log shows this? they also said as its overboosting on all revs it needs to be mapped

The graph showing the blocks you recorded with what I now know is vag-com. So block 2 shows the info and as I said yes you are right. What is the bhp output in you're car? What psi do you hold?

As far as I know its stock 180BHP still and it seems to hold around 8-11psi and peaks around 19psi on the boost gauge.

Something is wrong if it holds 8-11 but spikes at 19. Stock 180 It may be pushed to see 14 spike but would hold 8 all day to 6k and yes I have the ko3s. Sign of a bad n75 maybe.

I have a spare n75. The log 118 I think shows n75 open %

So it went in and when I went to pick it up I was told it never went on the rollers as it was running lean so would melt the pistons....I needed to buy bigger injectors as mine (0280155897) were only 217cc and it needs 310cc with the KO3S.* So I said I had the injectors off the car with the ko3s and when I did a part number search they were compatible with the APP engine.....he then told me without a remap they would melt my pistons. So I asked him to check part number of the other injectors....which he did......using*eBay.....and used*eBay*to show specs of mine....both showing 217cc....so he then went go the draw to get his aum injectors that would solve my problem with a remap....guess what.....same part number as my spare injectors (0280156061).....which eBay told him were only 217cc!!! He then looked elsewhere and everywhere said both sets of injectors were 310cc...so will be fine with the ko3s...They started going on about the fuel pump being the issue then. Im lost now as to what to do. They showed me VAG-COM block 032 showing correction of 1.9% on idle and just over 20% under load, I haven't had chance to do my own log and they have left the N75 unplugged to keep boost down to save my pistons from melting.....it all seems a bit too much like they really wanted it in to get mapped so I don't know if they are that great. I have got a fuel pump to pop in it and see if that makes any difference to the fuel correction but I'm not hopeful
