Good evening. Are you running @ Coopers?
I have no idea whom this TOMKAT dude is, but my son Matt is a 27 time National Dirt Oval Champion that helps everyone, at every track, on any car and with his knowledge that is why he wrote the Murfdogg Tuning guide so guys can take it to the track with them. He now owns an indoor RC track in Mooresville, NC called Race City Speed Factory. I've been running a slash modified, the same one since 2015 and use that guide myself when I lost.
Like that TOMKAT dude said, be careful whose insight you take, and that is about someone giving out info for a type of track one does not run. Thanks, Have a nice evening.

P.S. : Ist ROAR brushless national championships ever for 13.5 & 17.5 classes were won with Murfdogg Motors and MD team driver Andy Smolnick
