Re: Handheld tuners available?
SCT tuning is available for the 4.7s. I cannot speak for the WKs, but the 04+ Dakotas/Rams that have NGC PCMs are compatible.
As far as converters, yes, they are available....Pro-Torque is the company to go with. There are cheaper ones available, but they have a much higher failure rate.
Due to my workload, please do not PM me as I do not regularly check my PMs. Thank you :)
