Hey all

Wondering what the best mods are for excellent HP and TQ increase on a 2011 X5 5.0 TT?

I'm interested also. I currently have the AC Schnitzer muffler, but am looking to add headers, HiFlo cat and full exhaust etc and ECU flash. Interested to see what combo works best.

JB Stage 2! I'm going to do it on my 13' X5 as well.

I have a 2012 X5 50i. I have Dinan's stage 2 tune, I have a set of AR Design catted downpipes on order and will get the Dinan intercoolers and the stage 4 tune when Dinan has their next sale.

The single biggest bang for the buck is a tune. After the tune, a downpipe is probably the most cost effective upgrade. It will help the turbos spool faster, so you will see less turbo lag. I am hoping for 30hp peak increase with a 40hp-50hp gain lower in the range. The intercoolers will allow consistent power with less heat soak.

After these three mods, you will be chasing 5-10 hp at high $$$/hp. You can upgrade the compressor and impeller wheels on the turbos, buy bigger turbos. Port cylinder heads and intake manifolds, etc, etc.

I have a 2011 X5 xDrive50i with Dinan's stage 1 tune. As Brian425 posted above - single biggest bang for the buck is the tune. I am planning on getting stage 2 tune and considering the intercoolers.
