bought a used TDI of seller that bought it at auction due DPF code. had 161K miles out of the dieselgate warrant. it now has 171K miles
seller removed DPF installed Bussken down pipe.. and said it had stage one malon tune. I'm begging to think seller lied to me about stage one malone tun.. as best mpg I get highway driving is 37-38 mpg sometime 39..

I'm thinking getting my own stage one malone tune and installing it... what everyone else getting with stage one tune / down pipe.?
I don't drive it agressivly.. just mostly noral driving keeping RPM between 1200-1800 ...

On other VW forums I read that the tuners have a list of the VIN numbers for the cars they tuned. The comments suggested you could contact the tuners and they would confirm if or of if not the car was tuned by them.

You should do better than that. Is the exhaust flap disconnected and fully open?
You might need to do a full scan for codes since I think Malone might have disabled some of the CEL codes.

I have a Stage 2 Tune from MR Tuning and if I'm solely driving highway I can get atleast 43-45 mpg depending on my speed.
If the seller deleted the emissions equipment it would HAVE to be tuned otherwise it would not be driveable at all and would go into limp mode quite quick along with tons of dash light going off.
So its likely that it's tuned but you may need to scan it and see if theres any pending codes for anything. Check your fuel filter, air filter, basic maintenance stuff, etc.

There are just too many to list....
If it is deleted, it HAS to be tuned different from stock.

I have a sticky thread in the Fuel Economy section, take a look through there.

Also, make sure you have an accurate standard way of calculating your fuel use, repeatedly, over the span of several thousands of miles.
