I also have an IX MR, and I just dropped it off to have it tuned. I had an alky kit, 255lph fuel pump installed ontop of what I already have. No cams yet, but I was looking for just a little more power, not maxing the stock system.

Save for a new clutch, you will need one in a few weeks.

 

I use 104 Race gas instead of alky inection kit. ams wants 495 to custom tune. not cheap

 

Get the headstuds and walboro if your doing CAMs and turning up boost to 24psi and you dont need 104oct to run 24. i have been running 23-24 psi for 3 years now on good ol shell 93oct
