Default MSD Dis-4

Just wanted to make sure this right for my coil pack setup before I spend that much money on an ignition box.

It seems the stock ignition isn't up to the task of keeping the spark alive after 6300 under boost.

It doesn't say your car under the applications, but I believe there's some adapters or something you can use to get it to work. RPMoutlet might have the setup I saw for it. Have you tried a boost-a-spark or anything?

It does actually say ford mustang 94-2006 which seems stupidly vague since there are a lot of differences in those years. No I havn't tried a boos a spark. I'd like to get an msd setup so I can run a 2step and make some boost off the line plus solve the weak spark issue in the upper rpms.

They were at .032 at first then we pulled them and put them at .025, but it didn't help. I've seen the wotbox, but kinda figured if I need ignition upgrades why not get a box with a 2step built in and kill two birds with one stone. I just don't understand why they are so vague on the applications and details like they are...

Wow .025!
I'm good at .030 at 6500 and 17psi so IDK
I actually called those guys up and it's a very easy install

I may look into that. What plugs are you using? I'm running autolite 103s.
