No I don't have one. Therefore I don't know. Thus, i asked the question. I also see that your SRT doesn't have factory tuning. I'm sure that doesn't help

Well, now you know! He did say he wanted 500 rwhp in his first post. A bone stock 6.1 lists 14mpg city/18mpg hwy. Thats with a 5 speed auto tranny.

Mine has a AEM cai, Dynatech full tube headers with full 3" exhaust, high flow cats-mufflers and JBA cat back setup and a custom tune.
