Performance upgrades

[4.8isX5]

I have an '11 35i.

Not really expensive to do all of this especially if labor is cheap and it transforms the car, i have the following done on mine-

-VRSF downpipe
-VRSF Chargepipe
-Mhd Stage 2+ tune
-XHP Stage 3 transmission tune

Obviously before doing this you should be caught up on maint items-

-air filter
-oil every 3-4k ( i change this way in mine, plus FCP oil changes essentially cost $15 for shipping to return old oil )
-Spark plugs
-All ignition coils (delphi)
-Oil filter housing/cooler gaskets
-Valvecover if needed
-HPFP (if you have longer cranks its probably this, crank should be mostly instant/1sec)

I would get plugs and coils from FCP, free lifetime replacement all you really pay for is return shipping which is beans. Plugs will go quicker maybe every 20-30k with tune.

Even stage 1 or stage 1+, id recommend doing the trans tune. Increasing line pressures and such causes the clutches to do what they are supposed to and avoid microslipping. MHD and XHP also worked together on this option, so if you flash MHD stage 1 to mess around but later do the XHP trans tune, select the "tuned automatic" forgetting exact name in the MHD app, and reflash- takes under 2 min if you already did the initial flash.

Runs great, no complaints.

Awesome thanks for the advice!

and holy crap and did not know FCP did exchanges on oil! I would have been doing that for the past 14 years with my 740's. I have to make sure I can change my own with my current warranty. I know for my last warranty They did not except you changing your own oil, even if you had the receipts. Funny thing is for that car (GMC Yukon) I still take it to the dealer for oil changes instead of doing it myself. I can't buy the oil and filter for the price they do it. cost is around $50 for 8 or so quarts of full synthetic, oil filter, and tire rotation.

Do you plan on doing the VRSF intercooler?

wait, warranty?

You think that if you have a car that was modded years ago...maybe years BEFORE a warranty company sold you an extended warranty- that because the mod as there when you bought the warranty it 'doesnt count' or 'the warranty has to cover it'???????


No, not even a little bit.




People that need warranties should NOT be modding cars. IMO. Its a path to pain and tears.

Warranty came with the car, car has not been modded by me, if by anyone. According to my paperwork on the warranty it covers the car in the condition it was in at time of purchase...

Is there any way to tell if the ecu has already had a tune done to it? and if so what was used? Bimmerlink still shows a boost pressure over 15psi. I thought stock was lower. it would be nice to know if the ecu has been modded before dropping $650 on one of those JB4's.
