    what ever tune it takes to maximize it.

    are you trying to ask whether or not to get a handheld or full tuning suite like hptuners?

    well, if you aren't too confident that you will be able to learn how all of that stuff works, then get a handheld if you want to be able to make changes when you want. other than that, it's go to a tuner and have them tune it. only thing is, when you make changes, you have to go back to them to get it done and costs more money.

    My opinion is that with the mods and things you have done a handheld won't be able to correct. Your mods have made huge changes in airflow---you will need to be able to log the LTFT's for part throttle tuning and log the WOT AFR to get the optimum 12.7 to 13.0---most handhelds won't log or read that information so you won't know which way to go.I would recc. to go with a full blown tune--either dyno or driven. You don't want to guess at the WOT fuel ratio or you could damage your engine on the 1st outing.For example when i did heads & cam my LTFT's were off 18% and the AFR at WOT was 13.5. ----dangerous--- A year later when I put on LT headers the LTFT's were off 9% and the WOT AFR went to 12.4 --richened up.

    Hand held is for mostly stock car I would say, for extensive modifications to fuel trims as said before you would need something like HPtuner software, with HPtuner software you could always go back and adjust things for optimal gains and you can use it when you add more mods because once you start you cant stop, it becomes part of your blood. you will see what I mean.
