But if I recall there were a couple complaints about that one as well. But the individuals that o actually spoke to said they liked there Magnuson. FYI, AEV does not mess with them anymore..
In the end I did neither because I came across a Hemi swap thread posted by "Elusive" that seemed to indicate a V8 swap could be accomplished for less than $10k(but that is dependent on your mechanical abilities). So I did that. If you are willing to spend nearly $6k on an SC, for $1500-2000 more you could do a Hemi swap. And you can sell your 3.8 and trans for $1500+. And not to offend anyone with a 3.6, they are really not that impressive. I have driven a few stock 3.6's. Was disappointed.

I do need to get a custom airbox made so I can plumb my snorkel back in when needed. RIPP is well made and the install was fast and is reversible.

There is a guy locally that's really good at tuning never done a jk b4 but said be no problem. Told me he would dyno b4 and after see gain! Plus I kinda like the whine of a sc and the sprintex seems louder. Seems like the sprintex produces a little more horsepower than the maguson with the right tune.

Being based in Australia I called sprintex and enquired about the Diablo Tuner & ended up buying one from them and installed their shop tune , and I can't believe the difference it has made , pulls through all gears fuel use has dropped significantly it's a completely different beast, . best $400 I've spent since the whole kit was installed . If anyone is still using the hypertech I'd advise them to bin it . Jason
