was wondering what you guys think of installing one of those msd offroad boxes. I know it has multiple sparks which i can see burning more fuel. Is it going to give me more power or better fuel mileage?

 

I used one on my firebird. Actually, I got slightly BETTER gas mileage. The multiple sparks burn the mixture a bit more thoroughly. (only get multispark below 3000 RPM) Idle was smoother, throttle response on the low end was slightly better. All in all, not a bad investment.

 

I almost got one awhile back. The main complaint I read from people using them is that they went through cap/rotors a lot faster. Given how much of a B it is to change those on our trucks, I opted against it. However, now that I have the body lift, it is a lot easier. Might have to reconsider this again.
