Mike I don't think anyone outside of vendor would dyno just before and after DP. See below the thread link of a M235i owner sharing his dyno experience where he sees a 11hp gain (318whp vs 307whp) from HJS 300 cell alone on stock flash (10~12psi).

My tests were purely based on 100-200kph times with our abuse car. In early 2017 that car was on FMIC/decat and JB4. The best we did on E30 is low 9s on flat 17~18psi map. Couldn't live with the smell, we switched to 200 cell but nothing changed. We even got slightly better results - occasionally broke into 8.8/8.9s. Couldn't do more ethanol because of fuel pump limit.
In mid 2017, we loaded BM3 as BEF and installed WMI, trying to max out stock turbo at ~20psi (taper to 18). We did consistently mid to low 8s at around 80 IAT. Still beaten by a 140i on meth (low to flat 8s), we thought decat can help, so put it back on. But actually it was just loud and smells and don't improve power and 100-200 time at all. Till this day, that abuse car is still FBO on meth and stock turbo. We love that car. It's tuned up to 11, super urgent and ready to fight. Most importantly, it educates me well what M2 stock can do. BTW, on that setup it can barely survive one hard lap at Shanghai International Circuit (F1).
