Gilmore Coyote manual/clutch issues

Just out of curiosity does anyone know why the Gilmore Coyote will not launch properly when using manual/clutch setup? I have tried every possible combination of gearing and assists and cannot get it to launch properly in circuit or drag. Any insight is appreciated

I have no drama with it. Mine is fully upgraded and I would have adjusted final drive so 6th gear just starts to fade. I can check exact settings in an hour when I get home.

It launches decently in circuit at full throttle but not at half to 3/4. And for the life of me I cannot get it to launch correctly in drag, which is more my main concern. It launches just fine in manual only but is slower
