I reached out to Brian at JST and asked if I could go g25-660 and have it under tuned while I acquired fueling. He said the stock fuel system would be well within the turbos efficiency range and just be running low boost.Well crap, thats what i get for not actually looking farther into it. I bought a gen 2 2860. Oh well, for staying with stock fuel, my results will be similar.
Can ya do a summary of pros and cons for tuning with adding boost vs timing? I knew this differed per tuner but never thought past that lol.Boost was unchanged between the 93 and e30 map with the 2860. Just timing
Also, he allowed it to naturally drop a little bit. My WGDC is fairly low, he could pound high boost all the way to 7k. But Alans tuning style is less boost/more timing which is what I like. @rob99rt Is currently having a gtx tuned through JST and he runs a lot higher boost, with the tradeoff being lower timing. There are pros and cons to both tuning styles.
