i have turbocharged my r32 and before have never had any issues with this fault . but about 500 miles after my new tune  i get p1143 load calculation cross check upper limit exceeded, that keeps coming back every couple days. 
fuel trims are close to 0 just switched to e85 this tank.  im running ev14 550cc at 3 bar. and a stock mass air flow meter , stock compression, 4.5 psi. KFZW is stock and it still pulls up to -10*KW . switching to e85 made little difference in timing retard, but it felt like it gained about 50hp.

do you think this could be a hardware issue or do i need to modify my base tune. MLHFM? any ideas?
