Yup. So I basically have the MPI piggyback unit installed. Although, it's not the latest hardware revision, but it's what the MPI piggy is based off of.
I had the guy who did my exhaust install my two extra injectors before the throttle body.
I spent the weekend installing the piggy and removing my FMU. I'm running my stock MAF, BUT, i added in a MAP sensor so that I can see when boost comes on, so I'm not firing the extra injectors until then.
Right now, I'm @ 6psi.
I'm still tuning it, but I must say, this thing is pretty nice. So far, I'm not controlling ignition with it, and I'm not even touching my stock injectors (I don't care to), I'm just controlling the extra injectors with it right now.
Using the MAP sensor, it was decently tuned within 15 minutes of driving. I know MPNick isn't a huge fan of the MAP, but it works for me so far.
Anyway, so far it's doing its job. I still have to play with it to get the maps better, but there's nothing really wrong with them right now. I figure I'll tune them to a 12:1 AFR.
If your boosted and running an FMU...i'd reccomend picking up this piggy and an injector or two. It will probably cost you around $1K. Well worth it.
