I own an 89 GTA 350 TPI, I have accel injectors and msd blaster coil, but before I go cutting wires and drilling holes, somebody has to tell me that the MSD 6A box will make enough difference to justify the price and installation.


(This car is a daily driver. Only headers and exhaust are mods left on my list.)

Thanks any exsperience is appriciated.

 

Its all good, best I can tell ya. I've got one, its a difference you should notice immediately honestly.

 

I disagree, on a relatively stock motor you wouldn't notice any difference at all.
