Without one would it cause a car to just not boost and throw a map code as soon as it tries?

 

Whassap! The car will boost regardless but you'll get a MAP code, unless you get engine management that tricks the ECU or Hondata which allows it to read boost. But a Missing Link is cheaper than either of those. Got one for sale if you're interested...

 

I also have one for sale, came from the Vortech SC kit, only used for ~200 miles.......let me know

 

Thanks guy....but I already have one.
