Default y8 with boost acting funny now

have had my y8 boosted for about 4 months maybe longer and now its acting up.wat i originally thought was bein to rich or boost cut wasnt at all. i have no idea wat it is. on the dyno we added fuel till it was to rich and took away as much as we could but didnt do a thing. its not boot cut because i also installed a 2.5 bar map sensor and it did the same thing. it sounds like boost cut. i can get on it hard and it will do it and then i can slightly back off the throttle and it will stop but when i get back on it, it does it again. if i shift it goes away. i think it may be the ignition system. i will try to get it on film tonite so i can post it..

also while on the dyno when it did it we would look at the power graph and hte curves would just spike downward like 25 or so hp worth.
