Re: boost timing master
You don't need one. Those timing retard boxes are intended for a someone swapping in Turbo or SC into a NA motor running stock ECM with too much timing,
Our stock chip already have taken the timing into account. The stock chip has ~14 degree of timing at WOT. With 1 degree of timing retard per psi of boost, at 14psi of boost you would be running 0 degrees of timing. The intended market is for instance someone running 6 psi of boost but has 30 degrees of timing at WOT, so with 1 degree of retard per psi would be 24 degree of timing. .
