if I got my car tuned when it was mostly stock, would I notice a difference?

I would like to know this too....or if with CAI, headers, and cat back it would help much?

I say its worth it thats basically all thats done to my car and look at the times i run. Every other lt1 i run into has the same mods i do ex the tune. I am usually at the low 13's and they are mid's. When i use my nitrous then that a diff story. LOL

It made a difference for me. I'd say it's worth it.

It won't make you any slower and you will likley feel some difference. Also I know PCMforless will only charge $50 in the future for additional upgrades! I don't know about other tuners but I imagine they are the same. If you plan on upgrading you're car it will eventually need to be done, so why not now!

It can help. The stock a/f setting at wot is way too rich, and you can benefit from other changes like lowered fan settings, etc.

Definitely will help yes. Stock tunes are very conservative. They don't want any blown engines due to KR.

If you don't plan to do any mods in the next year or so, shell out for a tune. If you plan to mod, just hold out.

I did my own tune, and I won't lie, I don't know what I'm doing for the most part. It was my second try, my first was a TPI motor. Thankfully the ECM was basically the exact same so changing settings was familiar. Anyways to the point: With just installing 24# SVO (25.5#) injectors, my car woke up. If I had a 94 where I could tune more easily, I'd be tweaking more, but I'm happy where I'm at for the moment.

Cliff Notes: Upgrading soon? Wait. Going to be months/year, go for it!

On that note, if you're going to, then you have basically 2 options. 3 really, but we don't count Jet and Hypertech type chips (unless it's free). You have a Dyno Tune, where you go and get Dynod and all the readings are then factored into the tune, this I'd wait for more mods to do since it's not cheap. The next is a "mail order". You send out your PCM to Ed Write, MadZ or PCM For Less, and then they send you one back (with in a few days). They've been in the biz for quite awhile, and can do wonders even for a site-unseen bolt-on car

Also, don't buy those eBay "boost computers with like 4 wires and a sticker, or the IAT (Intake Air Temp) little diode mod. All that one does is trick the computer into thinking it's sucking in like 50ºF air, instead of 80-110ºf, so instead it dumps in more fuel. Yea, you get more performance, but it's pretty lame :\

I tuned 2 bone stock cars and gained .4 with the 94 Z and .3 with the 95 formula. Just pick up Tunercats and read, read, read on the tuning forums.

Wait4me offers free retunes so you can get it done now and just pay shipping to have it redone when you do more mods.

My nephew who owns a 94 z28,A4,bone stock everything,no cats, and still have stock choking exhaust system and air filter. With a set of MT ET Streets 26x11.5-16 on stock salad shooters, ran the best of 13.8 @98 mph in a 1/4 mile last month. And thats with shitty 2.0 short time limited by the stock torque converter and stock 3.23 gear. NO TUNING WHATSOEVER!
So, the answer is YES with some kind of optimum tuning, even on a stock engine will definitely give you some gain in performance!

Yes you should notice a differance.

you could also get your tune setup for some simple mods such as cai, low temp tstat,etc. if you're planning on doing them soon
