How much will a tune help?

[Cor6s]

I have pacesetter long tubes and ORY with Borla adjustable exhaust, k&n FIPK, and free mods, right now its tuned with a F.A.S.T. flash handheld tuner with its 93 octane tune +10% timing and 0% over stock power enrichment (only two things you can adjust with the box tune) im not using the nitrous yet because i know i need a real tune for that anyways but i am just wondering how much a dyno tune would help my current set up or if this F.A.S.T. flash tuner is any good really?

A dyno tune would help alot, with hp tuners you can dial it in alot more and while your there you can dial the nitrous while your at it. If your going to run nitrous then its best to get a N/A tune built around the nitrous so you dont have to re-tune or have an issue when you hit the spray. FAST tuner is ok but for the price they are new you could have a few tunes done.

yeah i wouldnt have bought the FAST flash but i got a really good deal on it with a set of rims so i figured it was definatly better than nothing, maybe ill try to sell it and get a dyno tune this spring.
