I use the hpi polished tuned pipe and stock manifold for nitro star 25 engine.

I have notised that my engine likes a rich setting. I have the HSN at almost 3t out (factory setting is 2 and 3/4t), LSN about 2t inn from flush. If i turn the HSN in to 2,5t it still does not bog at full trotle, but the temp gets higher and it has less power.
