Looking for thoughts on controlling boost timing. Inline 292 with a HX35 turbo-intercooled. The car is more of a cruiser than anything, so race car style ignition won't be needed. Boost will not be over 10 psi. Do I need something similar to a MSD 6BTM for timing control or is there something else more cost effective? The BTM has several functions that may be ideal, but I've never been down this road before.
