you will need a chip burned for any custom tune you get, unless you have some moates hardware or a tweecer (which is basically a chip, but programmable)
without a chip, your limited to dizzy twisting and FP adjustments and both arent the ideal ways to tune, the timing adjustment at the dizzy is nothing more than a global adjustment. and the FP changes are short term, eventually the EEC will adapt back to where it wants anyways (if you give it time) unhooking the battery at the track and clearing the KAMRFs will work good idling around at the track etc... the car wont ever learn anything. it takes stablized driving for adaptive strategy to kick in. also to note the EEC cant "learn" at WOT, but it takes the adaptive correction it learns from a different cell (IIRC its 50% load and 2500 RPM) and will apply that correction to WOT, it will take some time before you ever get the EEC to get to use adaptive there, and with a cleared EEC at the track putting around, i know it wont.
so at the track you can adjust FP, but other than thats it short term. after driving it a while the car will adapt back (assuming your tune is that close anways)
ANYWAYS i'd suggest a custom tune, with the proper inj settings and MAF info put into the tune, etc etc. and the car will be alot better off. should pick up quite a bit of power. with a tune who knows where the AFRs are? get them in check and smooth it all out and the car will drive better and most likely make more power.
with all the tuning i have done with my car. i am CONVINCED even a stock engine would benefit from custom tuning, ive done an experiment where i kept all the stock WOT fueling and etc (but had the rest of the tune like maf and injector stuff to my stuff to make sure things are accurate) and the stock EEC commands AFRs in the mid-high 11s and i know leaning that out a tad will net more power.
