By all means, it is all good information. Indeed running pure 100 octane+Torco is not the healthiest thing, however, replacing the original OEM turbos with Alpinas we noticed a yellow like slightly abrasive residue around the turbine and compressor section. This does no harm to the susceptible components with the exception of the O2 sensors, sounds arrogant although is not the intent. Another advantage to the setup is a 3 minute transition from MAP 1 to MAP 0 with JB S2 pr just lower boost when back to 93 Octane pump gas. It is all good....IAG.....
