I cant remember who was asking about this, but here goes. My mileage with the 370's and a heavy right foot average 17. 42 MPG city and hwy mix(50-50). Thats an increase of . 2 MPG. I will be taking a long trip to FLA. in March will and will report highway MPG. Im happy with the increase that the 370's have given me. Plus the powerOo. Oo. .
 
I'm just curious,



If you were interested in selling your old 215's, how much would said injectors cost an individual such as myself?

Thanks for the info! It was probably me that asked, I am pondering the purchase of said injectors or the dd3's. Still not sure, but leaning towards the 370s.
 
I have gone through one tank since the 370s installed. With #8 plate and some winter warmup idleing, I got 18 mpg. Some showing off for friends also. Tremendous power now.
