MRC Chips for the Audi urS-cars

Stage 2 Chips

Chips plus VMAP

These chips, for use in the 4A0 907 551 AA ECU (AAN engine in the 1992-1997 Audi S4 and S6 models) along with either version of VMAP, provide boost levels of up to 21 to 23 psig and fuel and timing management to provide power levels in the 280 hp range. Dyno tests have verified this figure.

This chipset provide the best bang for the buck value of all our chips. The Stage 1 chips don’t come close to the performance improvement of these Stage 2 chips and, while the Stage 3 chips provide much higher performance levels, the cost of the required added modifications (turbocharger, exhaust manifold, injectors, hoses, etc.) increase the cost of the Stage 3 mods significantly.
