In a first time I wanted to keep the A4 program and turn OFF the DTC's. But I don't know what kind of problems are related to this patched-up configuration.

Some kind of limp mode?
Lower timing?
Open loop?
Richer AFR?
....

My actual VIN is 2G2FV32G9W2220630

2 (Country = Canada)
G (Manufacturer = General Motors)
2 (Make = Pontiac)
F (Carline Code = F-Body)
V (Pontiac = Formula, Trans Am)
3 (Body Type = 2 door convertible)
2 (Restraint System = Manual Belt)
G (Engine Code = 5.7L (V8) MFI)
9 (VIN verification)
W( Model Year = 1998)
2 ( Assembly plant = St. Therese)
220630 = Production sequence

When you say "change 1 number in VIN so its seen a same car" you mean increase the production sequence by 1? (= 220631)
