I had the Range Device on my 13 SS with no issues. I only have a CAI. I purchased an SCTX4 and downloaded the 93 tune. I no longer needed the Range. A forum member told me even with my cold air intake only my car would be better with a tune from Dyno Steve....all I can say is WOW! Car is unbelievable now. You should check him out. You won't regret it.
