crazyandy did some math for me... my tdi-m is pullin aprox 6200rpm... at that point no more pull.. stock 98 02a, 3rd gear 78mph via gps.. 21psi of boost on the stock pea shooter tdi turbo too.... imo biggest differance.. no pre cup to drop.. no glow plugs required unless sub 20*f too.. but i have yet to drive a aaz to see how it feels vs my tdi-m..
1.9 AAZ 105-7tq stock compared to the 1.9 AHU 150tq stock. Stock the AHU would be way quicker, not to mention the always spooled k03 hitting max torque at 18-1900 rpm.
