The one guy that said "you have to pay to play" I understand. Also when you buy a car that has a $2600.00 gas guzzler tax (obviously auto), that's as big a red flag as anyone should need. But, when you have a thread like this one and there are such exteme differences I feel like the one guy said "something must be wrong".
I am in Reno, NV. 4000 to 4500ft elevation. Car at 800 miles, strickly adhearing to 1500 break in guideline. My DIC say's avg MPH... 27.5! CAI installed... first three tanks, mid 10mpg, fourth tank 14mpg, last two mid 11mpg.
While researching this forum while waiting on my car to arrive I read all these 93 octane post and I become obsessed with the fact that I need 93 octane. Well, there is only one station in Reno that sells 93 and 100 octane... $7 to $8 a gallon for 93 and $10 to $11 for 100!
So I research Torco additive. Factor the ammount needed to achieve 93 octane . Almost an entire can... 28oz, can is 32.
When I take my car to the shop to do the several mod's planned, I mention this to the owner. They personally own two completely modified SS's, have built two ZL1's to over 700rwhp... all at 91 octane! He said on the dyno they are getting plenty of fuel??? It's obviously the altitude.
But still, how can some of you have modded 700hp cars (and I'm sure your DIC doesn't read 27.5mph, be getting the kind of mileage you are getting?
Something is wrong!
My car is currently at the dealership having the entire rear end replaced (at 800 miles... see previous post) and checking out other problems that they can't find, so I guess I will address this issue whith them at my next visit.
