I may need a little more help now.

Enthalphy has not reply so I email H.Throttle and they gave me some advice. I told them I changed from stock cams to Tomei 260i/270e with valve springs upgrade. I also changed the intake, still keeping z32 maf but going with a larger and smoother pipe verses stock before. I also gave them the most recent dyno graph to look at and he said

it wasn't the tune.

I did have a boost leak and spark issues during the dyno run.

So am I a tooth off? Boost Leak? Timing?

The car runs strong except for the 4-5k rpm range. Anything beyond ~25% throttle around 4-5k, the car would break up. Beyond 5k and below 4, the car runs fine.
