I,m considering buying bd plug n power. do the results warrent the cost. thanks Al
Depends. What are you looking for? If you want a little more power, without getting into multiple modifications, I'd say definately yes, you'll like this, it adds power and can be removed if you change your mind. If you care only about mpg, you may or may not see a difference. No mechanical skill required - it took a few minutes to wiggle the plug off because it was tight and temperatures were cold so everything was stiff, but, you can't get much simpler. I made mine a little more complex by taking extra time to smear dielectric grease on the connections before plugging back together.
If you are looking for improved mpg, reported results vary from 0 mpg to possibly as high as 2 or 3 mpg. I installed a VA on a 2001 HO about a month ago, and think my mpg is somewhere between 0 and 1 mpg better. On the other hand, the acceleration is definately up, no doubt about that. I made several runs and timed acceleration from 50 up to 75 mph in 6th gear. It was ~15 seconds before VA, ~10 seconds after VA. In lower gears, it seems like as soon as you put your foot on the floor, it is time to upshift. Also, I think if I had been going to higher rpms, the difference before and after would have been even bigger, because it seemed to be coming on strong just as I was backing off the throttle to stay somewhere near the speed limit.
