I emailed Singh on this topic. They have had bad luck dyno'ing M5s. I have read elsewhere that other tuners have had similar issues.
I have had my E60 M5 dyno'd so know it "works" on the dyno. I am considering this ECU and, if I do it, I will get an independent dyno before/after AND do some 0-60 and 0-100 runs with the GTECH before/after. I think it's the only way to get objective data: dyno + street numbers.
It's just odd that, given people's obsession with performance, they don't try harder to measure gains. If the placebo produces euphoria, why question it, I guess.
If the M5 did not come with P500S mode (only P500), I'll bet I could charge $2K+ for a mod that "unlocked the power of the beast." In reality, of course, you just need to press a little hard on the gas to get the same effect for free....
BTW, I don't mean to bash on Kronen/Singh in particular (I will probably buy their product!), it's just weird that solid data is so hard to come by (from tuners in general).
