Hello guys,

need some tip. I have already done with tuning the engine , using GO 0801 pipe, inferno us sport rtr is now very snappy on the trigger with no hesitation. Now, my problem is engine sometimes dies, especially in the 1 hour A-Main? what could be the cause? I was using OS standard plug.... don' t remember if its P3 or A3. I was thinking it was getting hot (i dont have a temp gun) should i richen the LSN or the HSN?

thanks,
