I would say keep at the 110/120 mark and it should have puff of smoke as it accellerates ,not thick smoke but smoke.also when engine idles it should build up or idle should drop ofter 8-10 seconds ,my truck and buggies run on 25% nitro,9% oil and with this fuel after it builds up for 10 seconds and i throttle it it is usually a bit flat and on second throttle it is a clean rev.
Also almost forgot ,always set hsn for a decent speed and then the lsn.
my 2cents, hope it makes sense and helps.
