I have the 6.2 LT1 10 speed pushing my 7000 pound JKon 42" tires and I am very very happy to see 11 to 12 mpg and im not light on the right foot but dont drive like a gorilla. Hands down I love this conversion.
I have a LS3 in my 03 TJ with 60’s and Atlas ll on 37’s and I get mid teens if I’m slightly respectful of the skinny. I could probably get slightly higher but there is really no fun in that.
I have one of your conversions❤ 6.0 with Morris supercharger. I'm only getting 8-9 mpg with 37" tires. I have been trying to get into you guy to see what's up with it BUT NO SUSCESS. Really need you you respond PLEASE.
