Are you running a fan?
Drop the pinion a cog and try it.
Also reduce boost a bit, and maybe go up a cog on gearing for more top end.
Depending on track, you could maybe loose boost and add turbo timing for straight, delayed on full throttle for that extra down straight?
Just find the balance. TBH, 50% boost seems too much to me, but I don't run speed passion, and I tend to use Turbo rather than boost. Boost doesn't suit my driving.
