The only catcams Ive dialed in were 708’s in a 1.6 16v it engine, pistons at tdc and a dial gauge from zero lift to a set amount and that was your cams dialled in, made 155bhp on the rollers at noble with a four branch and a Peugeot sport exhaust with standalone ecu from memory, 25bhp was a nice gain on a NA engineI'm interested to know from someone who has done the cam timing with the catcam tool . At some stage I will try and make one , just need to try and understand the logic
