Mine are Siemens from Racetronix flow matched set.
I use the extender extreme chip and 3.5" MAF and translator, I shifted the blm's with the programming a bit richer about 10 numbers.
No issues at all, idle and drive just fine, lean cruise works great as well.
70% DC on pump and alky. around 113 mph.
I bought the modded ECM used.
Daily driver, no issues ever with those injectors, pass emissions flawlessly.
