as the same units. Most gauges are either psi or kg/cm**2. In your reported data you state 1.1 bar = 16.17 psi. If it is actually bar and not kg/cm**2 then your psi is 15.95. Please be carefull to use the correct conversion units, especially if useing different unit calibration gages, this is a relatively minor correction but if you are on a dyno with 91 octane every fraction might be important. Personally I wouldn't go beyond where you are, 411 rwhp on 91 octane is very good numbers, hell I don't have any more with a lot more mods.
