molds for tpi before retuning?
my 87 305 tpi/auto iroc is all stock.
i want to put a set of headers into a single 3`` exhaust and k`n air filters for starters then maybe a cam will be next. but can all or any of this be done before i have to `re-tune` or burn new proms. i don`t know much or anything about this `re-tuinning thing` so any info would appreciated
