Alright gents, new minor issue. I've got a check engine light, code P0172...running rich. I recently put in a boost control to increase boost (from 7lbs stock...according to the boost guage) to 14 lbs. It has the capability to be turned on and off (back to stock). I'm assuming this is relation, looking for confirmation. Should I be worried about anything or can I just clear the code and move on? Thanks.

I ran into this same issue when I installed my boost gauge and read 7psi and thought I had a problem. Your R actually boosts to 10 but it stays at 7 for the first gear or two and then opens up to 10. So you will need to turn your boost controller to 11 and you should be good to go. This is the first thing I did but ended up not wanting to hurt anything and just did the IPD ECU tune instead. Hope this helps.
