You need to tell us more about your car and setup if we are able to answer that; you have included very little information. What kind of engine is this? What mods have you made? Do you have an EGT gauge?
If everything else is stock, IMO, cranking up *any* additional fueling, especially the amount you are talking about, risks melting your piston tops. Although there are some up here that have successfully run hotter than the factory combustion chamber temperature settings without any problems, I would proceed with caution and not overdo it. A best strategy is to do mods that cool down EGTs first (intercooler, big exhaust) before cranking up the fueling. And then use and monitor peak EGTs with a pyrometer if you want to know how hot it is getting and want to know how much more room you might have to go.
If you have an EGT gauge, the factory pre-turbine thermal limit of the 1.6lTD, as published in the 1.6lTD SAE paper and also verified by me before I did any mods to mine, is 1500 deg. F. IMO, exceed that temperature "at your own risk." Note that this is a true "peak" and not measured while the needle is moving, IE: measured at wide open throttle with the engine braked as needed to maintain full fueling for an extended duration, IE: until the temp needle of the pyrometer stops rising.
