I wouldn't advise purchasing the cold air package without getting the Dinan MAF housing as a stock MAF is smaller diameter than the Dinan intake tube and to some degree defeats the purpose.

The Dinan Hi Flow throttle body will require a software upgrade on the X5 to get it to run correctly. The Dinan air intake will work with no modifications to factory specs on the X5.

This is how Dinan gets the 4.6 from 340/371 to 369/382:

S-Stage 3 tune, free flow exhaust, throttle body and transmission software 349/374.

S1-Stage 3 tune, free flow exhaust, throttle body, cold air system, MAF, and transmission software 363/378.

S2-Stage 4 tune, free flow exhaust, throttle body, cold air system, MAF and transmission software 369/382.

Dinan didn't make any claims of performance gains for any mods unless combined with a tune. However, we know that more, colder air in almost always helps as long as the engine adjusts for proper air/fuel mixture so there is likely some benefit from the COI alone but without the other S level components my quesstimate is 6-7/1-2.

I haven't checked recently but transmission software has been available. For $300 it is a great performance investment. I have no idea how anyone today can get all the Dinan stuff to get to 369/382.

Brian so you like the Dinan trans software? I have been thinking about getting this for my X5. How does it differ from the stock feel?

I snagged it as quickly as I viewed it. it shipped the next day and arrived 3 days later with all of the contents and instructions.

On another note, I was able to source a dinan front tower strut bar/brace from a X5 enthusiast in Canada kiji website for$210. For me that was the hardest part to find.

Damnnnnnn. I wish I had seen that. That's a great price for a strut bar!

If DINAN Automatic Transmission Software cures the transmission issues ill buy it in a second!

That's purely a guess based on problems that are posted here that I have not had, because of how more stress than the stock I put on components and how hard I drive.

Only other reason I can think of is the 4.6 has a different torque convertor that could make a difference and I have changed the transmission fluid and filter 3 times (about every 35-40,000 miles).

Changing the fluid on a routine basis I believe is more of the key. Waiting until 100,000 miles to change the fluid on these transmissions is a recipe for premature death. My 540It wagon with 190,000 miles had no tranny problems or leaks. I changed it twice in my ownership but the previous owner did it twice also. 45K,90K,130K and170K. I told the new owner they will want to change it at the 210K mark if they intend to get continued good results from the 540iT wagon,

I was planning on changing my tranny fluid every 25k-30k. So I am approaching that interval very shortly. I may drop the tranny oil pan and see what it looks like, new gasket, fresh fluid, and new hardware.

Guys, how can I tell if I got the DINAN ecu or tranny software/tune?
Recently, I got a new black on black 4.8is with DINAN air intake, strut bar and exhaust but I am not sure if it has the engine and the high flow throttle body.
I can check that with inpa but how can I tell it's dinan or not? Or the throttle body?

Btw, this new to me DINAN X5 is quite faster than my red one.
I might sell the red one or my daughter's 4.4... I will see. Still like the imola though.
