I totally agree with what you said. your right no off the shelf tune will be perfect for everyones tune.Speaking generally for the bolt on mods that most of us are doing these tunes will work just fine. If you have a more aggressive build/motor combo in mind you could always contact DHP or anyone the does PCMs (I dont know them all or if all are good. Some better than others I imagine). Also I simplly stated that DHP is the resource that I used with good results 13.3 HP to the wheels. By no means an end all solution but for me a good one. The original post was asking about PCMs and if anyone had used them. I simply gave my advice, I thought thats what we do here??? Get others opinions about parts or mods before shelling out hard earned cash. See what works and what doesent. Also Ive never seen an engine with an air fuel ratio as rich as 11.5/1 make more power than 12/1 Not from Honda's to 3800's, big blocks or small blocks no matter the RPM. But if You say so than Maybe Its true.
