Ive been having a fiddle and have managed to get alot more torque by adjusting a few thing hear in there
I have had a search and not come up with much.
I got the 405 Tubby to play around with Chip fat tuning (as its a shead load cheaper than runnig my MR2 Turbo for work
Any help or advise would be appricated, oh and the part i adjusted on my pump is right at the front and basicaly if you press the leaver down it cuts the engine, so I have adjusted the position of this leaver so that its more "open" if that makes sence !![:D]
