vlad_b Posted December 2, 2009 Share Posted December 2, 2009 What is the change in fuel consumption after upgrading stage1-2, and turbo? I'm driving 70+ miles a day, and trying to figure out what can I do without increasing cost of my commute. Most of which happens at 80mph on 6 mt which is around 3K rpm, I guess.

dudeondacouch Posted December 2, 2009 Share Posted December 2, 2009 significant, but nothing out of the realm of doable. however, if 5mpg is a $ issue for you, stg2 or a turbo swap might not be a good choice. /constructive suggestion Link to comment Share on other sites More sharing options...
subiedad51 Posted December 2, 2009 Share Posted December 2, 2009 I'm at Stage 2 (Catted DP, Perrin TMIC, Perrin Mid/Y, AVO Panel, TA Map) and on the highway I've seen a slight increase in MPGs if I'm just cruising. I get about 26.5 to 27 driving 75-80 (93 octane). Link to comment Share on other sites More sharing options...
dudeondacouch Posted December 2, 2009 Share Posted December 2, 2009 I get about the same(very similar mods), but it was a 4-5mpg drop for me. 31 highway stock. Link to comment Share on other sites More sharing options...

I get about 26.5 to 27 driving 75-80 (93 octane). So you actually getting better MPG??? My average is between 23-24mpg, 19mpg with aggresive city driving. But I rarely can get better than 25mpg on a higway at 80mph in 6th gear on 93 octane. Link to comment Share on other sites More sharing options...
vlad_b Posted December 2, 2009 Author Share Posted December 2, 2009 I get about the same(very similar mods), but it was a 4-5mpg drop for me. 31 highway stock. Do you have LGT? As I mentioned above, I rarely get better than 25mpg on a highway at 80mph in 6th gear... At least according to my computer. That's with stock drivetrain and significantly lighter than stock wheels:spin: I can get close to 30, if following truck closely, at 65-70mph, but 31? never.

Face Visor Posted December 2, 2009 Share Posted December 2, 2009 I average about 27 mpg mostly highway driving at 60mph. I'm stage 2 (catted DP, AVO TMIC, AVO Panel Filter, PDX tune). About the same as stage 1 and stock for me. Link to comment Share on other sites More sharing options...
vlad_b Posted December 2, 2009 Author Share Posted December 2, 2009 your aggressive driving doesn't help the gas mileage I'm saying drivign at constant speed in a strait line on a higway I get 25-26mpg at 80mph and 26-27 at 70mph. Just checked this morning again. What aggressive driving you talking about? Link to comment Share on other sites More sharing options...

CapnJack Posted December 2, 2009 Share Posted December 2, 2009 I'm stage 2+ (catted DP, AVO TMIC, AVO Panel Filter, SPT Catback, P&L tune). Stock I was running about 25-26MPG consistantly on the highway at 72-74MPH. After going stage 2+ I'm getting about 27-28MPG consistantly on the same drive and same speeds.

mightyS Posted December 2, 2009 Share Posted December 2, 2009 I have the 05 GT 5sp manual. Stock and Cobb stage 1 it maxed out at 31 mpg highway going 70 on flat roads. At stage 2.5 it got 29 on the same trip it used to get 31. Well, I also had 235/17 summer sticky tires. I switched to new all seasons at 215/17 and the mpg went back to 30. Tires do make a difference. Link to comment Share on other sites More sharing options...
ScoobySTi07 Posted December 7, 2009 Share Posted December 7, 2009 I'm running stage 2.5 (mod list in the sig). With the tune I just got, I get around 25-27 mpg keeping it below 80 mph on the freeway w/my 245 star specs. The tune I had before ran my car super rich and I was losing 3 or 4 mpg. The tune plays a big part in your mileage.

doccrowley Posted December 7, 2009 Share Posted December 7, 2009 maybe I oughtta get a tune... stage 2 5EAT and best is 21mpg freeway and avg about 17 city driving. Or maybe I ought to find a way to drive easy and slower than 90mph on the freeway and brakes to full boost to brakes to full boost as I'm finding my way through the old folks stuck in the commuter lane going 65mph ))))) Link to comment Share on other sites More sharing options...
