Punch from stand still

[Eggey]

All I run a TM2 V1, with LRP Flow esc 7,5 turn track & field brushless, and a Voltz 4000 with 30c burst, 21 pinon 85 RW spur, 1000 diff oil, I'm listing all this as I need a bit of help, my car just don't have that much punch on pull away or when you land a jump and you need to full speed down a straight. I've got the LRP boost on max, punch is set at 100% on handset, the clutch spring is just a half turn away from being fully closed, I just don't have great pull away any advice please on what I can do. I run on astro outside, oh and I've got yellow cut lp staggers on front and mini spike blues on the rear. Also the clutch plates and pads are fairly new.

Would it make a difference if I got a shorty with more of a burst, say 80c would this be the issue?
