No it does not require a tune. You can just bolt it on without other modifications.

Yes. Installed it in my 89 C1500 w/4.3 Throttle Body Fuel Injection. Runs Great now

I can only speak about the c5 2002, and I was only able to get the loaded tune from diablo. No adjustments for my car at all. I sent mine back , good luck

I have the 3840 and u have to go to super chips and down load the program wich took me like 10 times before it finally down loaded then I put it on my truck and it wouldn't let me tune anything it keeps giving me an error code but it will let me quick tune. I need to contact super chips because I want to send it back. I have a 2010 5.7 hemi I done the 93 octane quick tune and couldn't tell a difference in power and got less mpg

Increasing throttle will increase speed, but not by much. Best to adjust so that the engine is not "screaming" and go with that. It will cultivate pretty decent at a lower speed, but you need to increase it to till.

Sounds like your throttle input from your radio is wrong. Go through the set up again paying particular attention to how the throttle is set. At mid stick it should be at least 60%.

I don't believe they've released the 2014 tuning yet. I would email their support team and ask them for an update.

I only had the K&N; without a throttle body spacer but the car did have a performance ECM tune. So I can only say that the throttle response was great and you can really hear the intake breath with the open cone filter.

You will sacrafice fuel milage, mine went from 42 mpg to 38 mpg. But worth it to me. I've made mods to the engine and changed exhaust 2 or 3 times and the Auto-tune keeps it running at peak performance. No more costly dyno after mods!

You get a better throttle response. Also it sounds much better, especially if you upgrade your exhaust.

Nope. You will need what my installer called a "pigtail", which he got at Pep Boys, or NAPA for about $10. I still haven't come to grips with how much better my engine runs. It is surprising how much difference it made.

I have a 5.2 with a throttle body spacer, it was a little difficult fitting it on, but I got it on after about 40 minutes, any more questions just ask me,

Tighten the idle screw or loosen with engine runing I believe tightening it with gain you more torqe but losening it will get you top end speed . So if you tighten you will have better throttle responce in launch but it will decrease how fast you want to go . Loosen less power at. Start 1-10mph but witl pick up and haul @$$

I cannot speak for your engine, however with my 5.3, even with the program now removed. I still have to run 93 octane to keep the truck from skipping. Didn't do that before the programmer. Get a custom tune. You'll Be much happier

I had to tweak the carb on my 06 Sporty. If you have EFI then it too will need some tweaking. And I installed Screamin' Eagle air kit. More power instantly and way more responsive. If you do one you gotta do em all.

it got a little more responsive...maybe .5mpg better...maybe...but it sounds SOOO much better! Definitely a noticeable increase in noise under heavy throttle...it sounds like it should have from MOPAR.
