I've got a 1993 S4 with 115K miles. I want to add the "Intercooler Kit, Audi S4/S6 AAN" and "Chip Tuning Package, AAN/ABY Stage 1+". How much hp/tq would those mods add? In stock form the engine is very smooth, will adding those mods make it run rough?
Also, I'm wondering about oil pressure. The engine oil has been changed every 6k miles(always 10w-30 and fresh filter) since new. At start up the gauge pegs at 5 bar(for a second) then moves quickly down to 3.5 bar. At operating temp - 3 bar under load, .5 to 1 bar at idle. What are the oil pressure specs for the aan? Is .5 bar too low?
