After a while it becomes second nature and to some degree I agree with you, get in the car and drive/go. Bit I am glad to get those extra 3-5mpg without much effot.Driving isn't supposed to be such a chore. I am happy with the mileage I get just regular driving down the road. No way I am going to do that constantly every 15 seconds over and over again. You must want that extra economy pretty bad.
This is the first time posting anything so forgive me if it’s not correct area or not enough info. I have a 2002 Jetta ALH w/ 5 spd manual and it’s stock. It has 297k miles and the turbo is about ready to go. I’m getting High boost PSI faults so I assume the VGT is sticking on turbo. I also assume it’s leaking a little oil which is common for the mileage and age.
I will be driving 115 miles all highway one way starting this summer 5 days a week. I am currently getting 43 mpg.
I contacted KermaTDI about a new turbo they suggested VN-17, new injectors 520 and a tune. I was quoted $2k for everything I need. I told them I wasn’t looking for a lot of power over stock but an increase in mpg or at least stay with what I’m getting now.
My question has anyone do this upgrade ? What mpg gain if any did you see ? Is it worth putting $2k into a 300k car. Mechanical it’s a great car and the body is good. Interior is excellent. I will just be using it to commute. I only paid $300 for the car and have put 15k miles on it already.
Thanks in advance.
What was your mpg after it was "retuned" by the Dealer?Add slow down. Wind resistance goes up as speed increases.
My old 2013 Passat SEL (pre emissions scandal) did excellent on the highway at 65 mph. 53 mpg. On cruise Austin to Wichita and back. Right up IH35 the whole way. Don't take many road trips in the Beetle. More a commuter car vs the Passat.
I know you didn't ask me but in my JSW, I could hit mid 40s mpg around 73 mph. Tank averaged out around 41 for all interstate driving. Just came back from an almost 3000 mile trip and averaged around 37 on the interstate. About 35 for the whole trip using cruise when the monsoon rains weren't too bad. So dropped a little more than 10% since the fix.What was your mpg after it was "retuned" by the Dealer?
I found Bridgestone Ecopias gave me a 2-3 mpg boost in the JSW. I'm on my second set of them now.Some of the these techniques are only useful in a manual. My 2002 NB is an automatic. Since I drive like Grandma (5 car lengths back, 2 mph over the highway speed limit [right lane of course]), my mileage is as high as 41 mpg. I'd like to get that up, sure, without making extreme mods. It needs front end work (lower control arms and alignment) and new LRR tires, which could gain me 2-3 mph. Shocks and struts may be needed too. Will a skid plate help at all? There isn't one now.
I like the idea of an ECO tuning (after doing all the other fixes, of course). Green Diesel Engineering is no longer in the VW business. Has someone else picked it up? I'm not interested in a power boost for speed, just one that corrects the turbo lag and power distribution. It seems like it should make adjustments to the transmission too. Again, it won't happen until all the other things are fixed, if at all. But I like to know what the options are.
Alignment alone can make a significant difference, which if the ball joints are worn, the alignment is off. The skid plate will help as well, by reduced wind resistance under car. It also helps a lot in keeping engine bay clean.It needs front end work (lower control arms and alignment) and new LRR tires, which could gain me 2-3 mph. Shocks and struts may be needed too.
