Icon5 Built N/A B20a6 first dyno run (charts attached)

I've finally had a dyno tune performed on my built B20a6 (Australia) with:
Bored and Darton sleeved 84mm
JE Pistons (comp came out about 12:1)
Colt Cams Tri-Flow Stage 2 grind
Hurricane headers 4-2-1 with full exhaust, hi-flow cat

Chequered Tuning managed to achieve 100.7kw (135hp) at the wheel:

The tuner reckons that timing is very conservative (low 20s), but when he upped it, the car didn't like it (puffs of smoke from exhaust).

He reckons the engine has 7-8kw more to give up top if it breathes better. He said to start with a bigger throttle body, then look at custom CAI and intake manifold.

What do you guys think, throttle body first thing to look at? Any advice for next steps? My goal is 150hp at the wheel, which I know has been achieved with an N/A DD...
