Re: Msd dis4

i'm sure its crazy but its the only way i can find to be able to retard timing when activating nitrous. i have a tune for my procharged set up, i cannot have multiple tunes so i figured this is the only way to achieve spraying nitrous. the more im into it, the more it seems like its just not worth it. i originally purchased the msd 8921 and didnt realize that wont work and need the 89121, which are just not available at all.
