Tom,

I have your custom chipmaster diablosport tune on my turbo 01 ZX3. At M cNews we ran out of fuel pump duty cycle at 200 whp so I came home and swapped in a SVT fuel tank/pump. The CEL is on now. Someone at FocalJet said there was a different file for the newer fuel pump. Do you know anything about this and what I need to get changed in my tune? I live in Upstate NY so I cant drive down
10 hours for some trial and error.

Thank you,
Steve

The AF did go lean it was reaching 100% duty cycle at 5k rpms. Fuel pressure was down from 45psi to 30psi at 6k rpms. After 6k the AF was too irregular. I believe I have a recall pump that wasnt somehow covered under the recall so I just bought an 03 tank because it was cheaper.
