won't tune

[Scooby]

my trx pro .15 has always had a poor low end. If lean the low end it gets to the point where it won't idle if i go richer it just makes it worse. When i give it wide open throttle it bogs slightly and then goes.
Does the diameter of fuel pipe make a diference to engine settings the fuel pipe i'm using is larger diameter than standard

If you are running a larger pipe, it will change the way you engine burns fuel. Your best bet is to call traxxas and find out what it is they want you to do. Also, get rid of that silly air cleaner that traxxas sends with the pro.15, and get a high performance one. It helped my engine's performance.
