Review on πŸ’₯ Innovative Performance Chip/Power Programmer for Cadillac Seville, STS & STS-V (3.6L - 4.9L) – Enhance Fuel Efficiency, Boost Power & Save on Gas! by Mike Robinson

Revainrating 1 out of 5

Causes problems with Vehicles

The product was horrible causing a very rough idle and keep alive error. Disconnected and everything as usual, reconnected and the same problem. Wouldn't recommend it to anyone. No increase in performance or mileage. Not a real programmer, just a resistor in there.

Pros
  • Automotive
Cons
  • Modern
