Well, pulling timing will mess with your tune no matter how you do it..

Try a search, we have covered this recently so much that most will likely bypass this thread. The HSW Interface is the bomb these days, imo.

Timing Tuner, Timing Twister, or HSW Interface.

If you aren't wanting to adjust the tune, I would go with the Timing Tuner.

This will give you the ability of pulling timing only when the kit is active, it can pull up to 15* without having to adjust your tune.

the interface can only pull up to 4 degrees on a ls1 to me understanding and up to 7-9 on the ls2's. So if you are wanting to go above a 200 shot I wouldn't look at the interface, but if you are looking under 200 then you can't go wrong with it.

The interface can pull 3 degrees on an LS1, anything passed that and you can do so by adjusting the IAT spark advance table.

here is a link to the interface and some good information on it.

We also carry the timing tuner which i think will work well in your situation

forgot that the interface only allows up to 3 degrees on stock tune...
i use hptuners and have it set to pull whatever i want by adjusting the tables.
its a good feeling to not have to wonder about how my maf is reading my dry shot.
