As mentioned, the GC wrx plugin board can't do boost & ISC. That IMO...for essentially the same cost as the SM4 and less then the LinkPlus G3 is unacceptable....but that's my opinion.Brat4by4 wrote:Josh, is there a reason you are only looking at the SM4 instead of the GC WRX drop-in box? That should eliminate most of the problems with Autronic that have been mentioned. Not to mention near plug-n-play ability.
And honestly, what it comes down to is what tuner are you going to use and what are they the most comfortable with?
The plug & play thing really isn't an issue to me. I'll make whatever I use plug & play for my application.
You're exactly right about the tuner. That makes a difference.
