basic tune or dyno tune??
I have a 07 base mn6 that is completely stock, over the next two months i plan on installing a vararam with paper filter, Port the stock intake, 160-t-stat, NGK tr55's gaped at .054, and ZO6 manifolds/mid pipe reduced to 2.5" before the over axle pipes. Any other basic "low cost" mods i can and should do while i'm working on it? Anyway i probably will never go with headers/ cam/ heads ETC.. on it. Is it worth the extra cost to go with a full dyno tune where the car is on the rollers, or with these mods is the basic flash tune/mail order tune the way to go? I really would like the tune to take advantage of the vararam and the 93 octane and keep the timing pull to a minimum.

i had a diablo tune when i first got the vette and it was stock. i got a custom steet tune a few months later i have to say the custom tune was much better at least as far as the butt dyno was concerned. i felt like the car made more torque for sure put you back in the seat alot harder. i dont regret trying the diablo because i picked it up here for 260 and sold it for 220$. i know there is a guy here who can build a more customized tune offf the diablo but i would try to find someone who is a good tuner in your area.

How the tune doesn't matter. A dyno is a tool, nothing special. The thing that makes the difference is the tuner. You can have a complete crap dyno tune, or an awesome tune that never sees the rollers. Mail order, street tune, dyno tune doesn't matter, who does the tune does. Shop based off tuner, not "style" of tune.

Forget about a flash tune using a tuner. Save tour money and contact ECS and mail in your PCM and have them flash it for 150 bucks. The mods you have are basic bolt ons and they would be able to get the tune dialed in 99% perfect as they have tons of files saved form cars that have similar mods to yours. With your mods and a tune from them, you should see 40hp or so. They will also adjust some of the torque management making the car feel and act more responsive. It's well worth it.

My opinion is if you want to save some money, then a mail tune is certainly less cost. But, if you're going to all the trouble*, what you don't want is something that doesn't optimize your add ons. *Kinda like what "boomer" said: as long as you have the underside of the tunnel exposed put in some thermal/noise reduction.
Like so many things tho, it isn't all about the technology as much as it is about the professional administering it. For that reason, I do agree w. unreal and dcasole. You want someone who hears your words, your concerns and knows how to optimize your setup while leaving a safety factor in the tune for "extraordinary circumstances" that you may encounter.
Good luck and enjoy the car!

A diablo tuner will allow you to flash tunes to your car, not adjust parameters. That's in the tune, now something you can mess with on the device. And I recommend a place like ECS for the tune over the generic handheld tuner for a better calibration.

This is how INTERNET URBAN LEDGENDS get started ... help me stamp out URBAN Ledgends
i can richen up or lean fuel , and many , many other items in ECM tune ,you also can access the TCM and make adjusts to the shift points and pressure, in D or in S mode , again , many many other parameters in the TCM tune , these are the same parameters that are adjusted with the CRM software used by Tuners ...
So yes , yes you can make adjustments to your tune or a custom tune using a Diablo ....
