When you guys say tune you mean bring it somewhere...but what exactly goes on besides multiple dyno runs?? And how much does it usually cost?

They adjust settings in the computer for more performance like fuel curve, spark, shift points, fan temps, as well as tuning out o2 sensors or egr if need be. Depending on what adjustments are made and how many dyno pulls you run the cost can vary. Where are you located?

Some self tune with EFIlive or HPTuners, others take it to a speed shop. Typical dyno tuning runs $125-150 per hour at most shops in my area, and it will usually take at least 2 hours, depending on the person doing the tuning, the mods, and any issues they run into. A good dyno tune can easily free up 15-20HP on most cars, more on modded vehicles. Besides gaining extra power, the car will gain acceleration due to improved shift times and pressures if it's an auto.

Unless you know alot about mapping/air fuel ratio/timing id pay the money and take it to a speed shop, afterwards your engine will run great and your car will be smooth and set up how you want it. what you could do is plan on spending about 500 bucks and be there on the dyno with the person that knows what they are doin, and have them explain what they are doing and why, what the outcome will be for different figures that he inputs and if you feel comfortable enough then you can buy your own HPtuners or EFI live like jag said and whenever you want to add something else to the mix, bigger injectors, nos, heads, whatever then you can retune it your self with one of those products using what you learned from the dyno guy-Mike

yeah it's better to just get it tuned professionally. a dynotune will cost $450-$500 depending on where you take it. if you plan on adding serious mods to the car i would wait until those are installed unless you're just looking to get baseline power numbers.

They're handy for changing everything from shift points, gearing, tire sizes, fuel trims, and spark, and also for datalogging and troubleshooting. I highly recommend either. You can do minor tuning yourself, but for something bigger like heads/cam, dyno is the way to go.

X2 I would say whatever you can afford to throw at it to go ahead and do it right then and there, say if your planning on switching out the heads/intake/cam valves/ whatever then you should start buyin all that stuff and once youve got it all and the extra money for the tune, bolt em all up and take it to the shop, you would be amazed what the right tune can do for an engine, basically imagine the best your engine can possibly run riding the line of power/reliability/longevity and he can tune it however you want. anyways just my $.02

If you have to ask what tuning is, please don't attempt to tune your car.

you need to understand that if you dont know what your doing and you do try to do it yourself...Ive seen engines go boom...just take it to the pros and see what you can learn

Hahaha, I was thinking the same thing and was about to type it when I saw this post.

OP, $400-500 for a good dyno tune around here. If you're paying much more than that (unless it's by the hour and they run into problems), you may want to find out why it's more than that (ie try to find another shop and get local opinions). If it's much less, make sure it's either a special deal going on or they're giving you the kind of time and attention you need for a dyno tune and not rushing it to get you in and out.

Post in your local area's forum for opinions and advice. Good luck.
