Checked my spring and im on the yellow spring no shim and 19psi boost.forge says that's just right and will need the blue spring once 22psi reached .I'd do ya tmic now instead of wasting time messing with other stuff. Im probably going to do that on wednesday night. Might aswell try the simple stuf...

Ok so tried the red spring before and did some datalogs. Only really seemed to bring down the WGDC another 0.5% so no real difference so ive refitted the blue spring with 1 shim. So tomorrow im going to refit the standard recirc valve and see if it makes any difference. Anyway here are the logs from...

What modifications have you got?

It is at the same rpm as last time which is strange as i reduced it already. I'll reduce again until it's gone but maybe you should think about a grimspeed or equivalent. I noticed that aswell. What I've done is flashes the base tune that comes with the software but with the MAF calibration changed...

Here are 2 more data logs from the new map that Skiptowncat has sent me with the load targets turned down to try and reduce my WGDC down from 100% but unfortunately its still at 100% :( Below are the 2 logs. IF anybody has any idea what could be causing the problem then please make any suggestions o...

You're flowing around or more than 250g/s which is probably the limit of your K04. This turbo can flow even more than that (some managed to push up to 280g/s with it) but it also depends on how worn your turbo is. the Boost air temperatures are also important, the hotter the air the higher the volu...
