Warping Tracks That Aren't in 4/4

Hey guys,br
br
I’ve had an urge to remix an old guitar instrumental into a liquid DnB track and am struggling to warp it correctly. The track is normally at 150 Bpm (which is fine), but it is also written with a time signature of 3/4!br
br
Ive tried using the straight warp method and tweaking slightly. Ive also tried manually moving warp markers every bar but that failed aswell.br
br
I was wondering if there are any tips out there that could help me get this track warped and working properly?br
br
Cheers!!
