[QUOTE="decipha, post: 15019730, member: 74327"] I post my own results from hands on tuning and experiences, if your mileage varies thats great too, I always like to hear what others have found as well, it seems as though most dont like to share because this happens and they get called out on it, I dont mind sharing and if you've found any of my info to be incorrect please let me know, in this case though I have found most of the 4 valves Ive tuned to like 27 degrees or there abouts, of course there will always be exceptions but thats what I start from and go from there 200 load isnt good because you cant have efficient spark control in that transitional range where it hits 200, nor can you dial in the failed maf PCT_Load table and most importantly you cant put any overboost protection in there in case you loose the reference line off the wastegate or decide to turn the boost up after the fact, its just not safe, I have no problem kicking up sarchg (engine size) to get load down when I hit 200 I usually multiply sarchg by 1.5 and cut back my spark scaling by the same 1.5 and fn035 by 1.5, it usually works out fairly close also keep in mind the mbt table is modified by the other tables, just like the borderline knock table the value in the cell is not what you will actually get if you dont cross calculate the modifiers, not saying the mbt modifiers are in effect at a normal operating temp but just for reference, also keep in mind youll see identical engine setups with different mbt values, that can be a good starting point but shouldnt be regarded as an absolute mbt chart [/QUOTE]
