My car runs on all stock stuff except the msd box . Stock dist , coil , parts store cap and rotor . I disconnected it one time trouble shooting and noticed a big diff just regular driving .dont know what to tell you guys,, it was blowing out the spark pretty bad over 3000 rpm on the dyno. Hooked up an MSD box he had and it cleared it up. i've known my tuner for 25 years. He tunes Tony Alm and many other racers. I have the Crane Hi6 and coil that I was going to install this weekend anyway. as its the stock original coil.
