I have tested the diablo tune for my Z51 and I loved it.
I'm installing a set of LT headers and off road xpipe.
Can someone modify my tune to delete the rear o2 sensors ? I don't want to change anything else, the car runs great, good mpg and it's my daily driver.
I live in Europe, there are no Corvette tuners around here to do a custom tune...

Get a HP tuners Suite and you can do that, and much more later if you decide.

Contact Diablew (Monte06SS). He can do a custom mail order tune through the Diablo for $150 for the added parts and cat delete.

Lew does great work and it couldn't be easier since you already have the Diablo.

You will need the front o2 sensors turned off with headers and off-road X-pipe. The rear cats are not monitored on USDM cars, not sure about European-spec cars though.

I think you mean turn off the rear O2 sensors.

You never turn off the front O2's. They supply the PCM necessary feedback on the A/F ratio.

In HP Tuner, you actually stop the PCM from turning on the Check engine light or setting a code when the rear O2 sense the cats are not efficient enough.
