The Mod That Increase 40 Plus Miles Per Tank To My Cayenne.

[RxPorsche]

Well at first I do it for the horse power increase, but after that I begin to realize that the miles per tank increase in like 12%. Before the mod it gets 290 to 300 miles per tank on average and now it have increase to 340 to 350 miles per tank. I did not believe it at first so I did not post for like 4 full gas fill up.

Here it is, not the most beautiful but it does the job.

The last picture is the only other performance mod that my Cayenne have.

Hi -- more detail would be much appreciated -- what mods you did, what the pictures represent, etc. Thx.

Thats right, Puerto Rico :clapping:

So you deleted both cats? How much low end torque do you think you lost? I deleted the cat on my first 944 and i lost so much power off the line that I regretted it.

Loren, are you asking about residence because running without any cat converter is illegal in the USA? The secondary cat delete pipes available from vendors are legal, correct?

[Loren]

Two reasons - one because most US states don't allow you to completely remove the cat. Two - because US/Canada cars are using (software and) sensors before and after the cat. So unless you reprogram a US car you will get a CEL (and faults).

Got it... then I have to wonder about the accuracy of this listing from a trusted parts supplier.

The cats with sensor control (regular) are pre - cats and can not be replaced by a delete pipe: 1) environment values not longer realisable 2) an error code is put. The secondary cats (irregular) auxiliary, can be replaced by delete pipes with no error code set and EURO 4 norm narrowly realisable. I have no idea concerning US operative environment values.

There is other 2 cats in place, the cayenne have 4. There is no lost in torque my dynobutt just fell like the truck get to boost a little more rapid. :thumbup: No codes here. :thankyou:
