Hey guys, as the title states when I'm wide open throttle on full boost (4000-7500rpm )it misses, coughs and splutters and does not perform at all pretty much all of the time, 95%. And also when quick shifting between gears at high rpm like you would when racing, it cuts out for a split second. Its only been happening after its re-tune. I've taken it back and he assures me its not detonating but thinks it could be cooler piping squishing or the fuel pump.....
Just after any useful input on how to solve the issue....
