Mod order / SCT Tune

obviuosly u never bought one then. i know i gained over 15rwhp from it on my custom 93 tune

Sounds like a very logical progression of mods to me.
I still need to do it, Oh well just up the nitrous shot and go from there.

"When to get a tune" This comes up quit a bit, and most of the responses are from people who have no idea what is involved in the tune especially a mail-order (non dyno tune). Most people tend to think they are getting a tune specifically made for their headers and cai, so let me clear a few things up.
For most bolt ons there are no special tuning changes that need to be made as far as power goes. When creating a mail-order n/a tune basically all that is going to happen, is the tuner is going to change the base fuel wot ratios from the stock 12:1 ratio to 13:1 and change the stock timing tables by a predetermined amount. This is regardless of what exhaust mods or intake mods you have because the tuner assumes all of your sensors are functioning properly. Now there are a few non-power related changes that may be made according to mods, like the speedo calibration, and turning off the rear o2's for an o/r midpipe. Most of those types of changes can be made with the handhelds anyway. Another huge benefit is the changes they will make to the adaptive strategy, that will not only smooth out the car, but will allow it to adapt better to any future changes. So what it comes down to is if you are getting a tune via a chip, you don't want to have to pay for all of the reburns for gear changes, turning off the rear o2's, etc. If you are getting it via programmer where you can make these changes and plan on staying n/a then I wouldn't worry about it being to early to get a tune.

Makes sense. I didn't know if different mail-order places do a better job than others. I've read that places like Modular Depot use tunes they've created based on their research, and they upload those tunes. So I thought a reputable tuner like that might offer a better "mail order tune." But I'll admit I don't know much about it. Guess my best bet would be to actually call MD since they're local or just go talk to them about it sometime....see what they recommend.

MD would be a good choice. Not all tuners are going to make the changes to the adaptive table, but most SCT tuners should.
