Both the ProCharger Systems and Tuner Kits can add 150 or more horsepower to the Challenger’s potent 6.1L HEMI engine while still running high-quality pump gas.

Well lets just say its night and day don’t know how accurate the SRT pages are but the hp has read up to 428 hp. I’m going to see if I can get a re tune to be more jumping of the line. I have 14 RT

there’s many more factors that go into it rather than just putting a boltt on thing. most of these guys dont have a 3.5 yeah it’s true if you have a high our V8 a lot of those things might help. More free flowing exhaust on 6.1 l V8 is going to give it substantially more hp.

A CMR tune is done by a qualified tuner using CMR Software. Basically you apply a tune from Diablo and do some data logging. You then send the file to the tuner and he will tweak it based on your data. This can go on for a couple of times. HemiFever Tuning is one of the vendors here that does this. Hope this helps you out a little.

No matter which canned tune you run, the 91 octane tune or the Diablo tune (aka 93 octane tune), there are 2 rules you need to abide: 1) run the proper octane for the tune. 2) datalog, datalog, datalog In my experience, the 93 octane tune will set the WOT fuel too lean in the upper two RPM ranges, resulting in lots of KR when doing WOT runs.
