              He. I use new tfsi coils. Last summer there was these 1.8t coils. No change for engine working.

              Injection are EV14 and injection size is 1100cc. What it shut be in these injection. I thought this field is only for information.

              I use E98 fuel.

              Basic setting for ingition have been checked many times. And it shut be correct.

                aaa,e98 fuel,that explane 1100 cc injectors
                i see that your ignition dwell setting stands on 1.98 ms and 1 on map scale
                i have also tfsi coils and my settings are 2.5 ms and 5 on map scale but maybe this is normal with other fuel ?

                  id say you can get more timing in there on cruise to lower the egt. e98 is not the same as our normal juice i presume.

                  i dont know what turbo you run but at say 3400 rpm and 80kpa i run about 6 degrees more than you.

                    Hello.

                    My turbo is CT355 with normal bearings. EM is wagner. Original wastegate.

                      so id say fairly similar to my sc61, wagner tubes, stock gate

                      whats your egt on cruise. also seems like the timing in that map on boost could take a few more degrees. think i get like 17 degrees at 2 bar.

                          ok

                          id get egt gauge. while your fueling may be good id say your timing is way too low, for sure in some areas of the map. get a gauge quick before you damage stuff.

                          i dont really want to say "do this" as i like to see these things measured with feedback but id make some cans as described on here in other threads and add a degree or 2 to start with anyway in the cruise zones. see if it helps.
