Looking to buy a S2K within the near future. Would prefer something that already has some heavy modifications done to it. One of my major concerns would be driveablity and MPG's After modifications. If some people could tell me their mods and how "close to stock" their car drives and if their gas mileage improved or took a hit after being turbo'ed or super charged.

 

About the last thing you should be even considering is MPGs when going FI. But to answer the question, my DD numbers have dropped (to about 18) but highway numbers stayed the same, if not better.

I feel my AEM EMS tune is better than the stock tune.

 

Just thought I'd ask. I don't want to get into anything without knowing everything about it. My current DD is a V8 so couldnt be much worse

 

your mileage will vary depending on how you drive it.

for me
NA
18-20 city
27-28 hwy

FI
12-18 CITY
25-28 HWY

 

Better then my 13mpgs with my GTO so I'll take that lol

 

I never monitored my MPGs after I went F/I, but ever since I've had my SC installed, I tend to accelerate aggressively, every chance I get. Because of that, I'm sure I'm getting much lower MPG than I could be getting.

 

Well that's half the fun of having a Supercharger.

 

mmmm GTO. 5.7 or 6.0?

friend had one with headers , tune, CAI, stall, and spray and ran 10's. car is abeast.

 

6.0 with cam, headers, test pipe, clutch and some other random stuff. Put 430 to the wheels with about $2,000 so I'd call it good enough lol. I'm selling it its in the FS forum.

 

Check the link to my Fuelly account in my signature. I have documented my gas economy. I rarely drive all freeway. So all my driving it practically done on local roads where speed limits are under 50mph.

I believe I am supposed to get better MPG, but I don't. That is something my tuner will work on when I get re tuned in a few weeks.
