Rail pressure demand will vary as every car is mapped on its own merits, we dont have a generic stage 1 or 2 ready made setting. But typically 112-120 bar if no uprated fuel pump is fitted. We do request about .2 bar more boost than revo stage 1 when set to 9.
Power from car to car will vary, my own k03 gti made about 240ish stock on stage 1 equivalent and 263 stage 2 with intake and downpipe. Look at the variations in stage 2+ k04 for example, some struggle to see 350hp whilst others with the same supporting mods on the same dyno can achieve 380hp.
And stage 1 with 250+ bhp isnt rare, I have tested k03 cars with maps from plenty of tuners (mainly independant and not the big names) that make 250-260hp, just because the big names cant/dont push them this hard with their ready made maps it doesnt mean it cant be done. with a few hours of dyno tuning a custom map will often outperform the big brands.
The dyno at RStuning reads virtually identically to our new dyno ( we tested a car this week that made 178hp and 272ft/lb there and 181/275 on ours so would be a good comparison test. This is to be expected as nearly every dyno dynamics reads the same (except JKM who I see getting results far lower due to the way they run the cars, which incidentally different to every other dyno dynamics operator I have seen, but the method of strapping is a debate that will go on for ever. Most however stick to the reccomended method that dyno dynamics train you to use) and other than strapping there is no way to make a dyno dynamics dyno give a false reading that isnt clearly obvious on the dyno graph i.e altering the barometric pressures or intake temperatures in the dyno software.
Its easy for people to sit behind a computer and dissbelieve russ's figures but thats life, but until his logs are taken the cause of his problem since fitting the intake are unknown, but my guess is that he is getting fuel cuts.
