Unfortunately I called and talked to spartan diesel several times about my 2011 and told them I had the sinister delete as well as a cai and 5" flopro with all deletes, they assured me that the phalanx would work no problem...after buying a coolant temp sensor and paying my local ford shop diagnostic time etc, we figured out that you need another part to use the phalanx without check engine light...I've called spartan several times to return my phalanx based on the fact that I was told by them that it WOULD work flawlessly with my mods and it doesn't. Not have I not gotten a response from the owner after leaving several messages but also the gentlemen I talked to said they knew it would need additional parts to function properly. The truck did feel nice and crisp with the spartan tuner, I'm just not willing to spend an additional $130 for another part. Plus it was a major pain trying to use the IDS on the truck, the spartan tune had to be removed in order for the IDS to communicate, a 20 minute process each and every time. Based on this experience I decided to stick with my mini max and I've ordered the hot x tune from spe. We will see how it goes. I hope this helps you, Good luck.
