Well. anyway... clamped wheel?!?! You can't clamp a compressor wheel... Well you can but then the turbo wouldn't work lol o_O.
Clamping refers to making the ECU see a false reading, intentionally. Be it using a diode to "clamp" a pressure value from the MAP sensors, or from a module (CMD). A reflash would just reprogram the ECU.
BTW a 19T wheel on the turbo, without any type of tuning won't really do anything, besides just hitting peak boost lower in the RPMs. Might cause some boost spikes, if you light it up, but then, you would throw an engine code.
Your understanding of the OBD2 system is confused.
OBD stands for "On Board Diagnostics," and is primarily used to diagnose issues. Tuners just utilize the "reprogramming" feature that the factory/service department uses, to reflash the ECU. The reason why there is a "2" at the end, is because the auto makers standardized the whole OBD system, and its the second major revision.
If you are getting the values directly from the ECU, from the diag port using a OBD scanner or a gauge that connects through that port (something like an infometer, from my understanding), and have any of the sensors "clamped" (defined clamping earlier
), those readings will be false, thus useless above a certain value.
