99 shanghai cutting out above 4k

So after my alternator deciding to work again I took it out for a drive for some tuning but for some reason I can't get past 4k. Overboost is set at 200kpa and I never reach that. Even weirder is that in first gear it pulls fine to redline, it just stops it in second and on?? Afr's aren't perfect by any means but I wouldn't think that would be the reason.
