2014 Cruze long term review

That's against the rules...

What would you like to know?

Throttle lag off idle is still kinda there but not dangerous anymore. I can spin my 245 width tires through 2nd gear from a stand still. 4th gear 30-70 is faster than the old 0-35 with a boosted launch. A bit of a deeper exhaust note.

I am thinking of taking it from the downpipe flange to where the SCR catalyst is with 2.5" stainless (or is stock 2.25"?? Gotta check), then increasing to 3 or 4" through the exhaust tunnel, Y before the rear axle, and dual 2.5" with chrome turn down tips.
 
So, I ran it today.

Absolutely no change. Best was 2.212 60', 10.410 @ 65.57 1/8th, 16.436 @ 82.44 mph.

Now, I can say from 2200-3700rpm has a huge increase in torque from a roll but from a standing start, no change.

Ya know, I'd be happy with that. Only things I really care about are:
a) better fuel mileage
b) loss of engine "weight" and the associated potential for failure of those parts

A) With 245/35/20s, I saw quite a bit reduction in mileage. Before with the stock AL wheels and the 215 pizza cutter LRR at 80mph, I would get 43-45MPG. After, I would get 38-40mpg. Still not bad IMHO. now it seems to have returned to stock mileage but with bigger wheels
B) Mileage increase is a direct result of the weight reduction and as such, the CEL fell off too

I havent seen a big reduction in mileage from the 215 LRRs to my new 235 Kumhos. Maybe 1-2 mpg? Considering the weight difference between the two, its surprising.
