whp estimation 2.3 35r aem or stock ecu?
I've used both ECU's and didn't really care for the tune on the AEM. As one post said an ECU is only as good as the tune. The new shop preferred the stock ECU. The owner informed me that he has tuned EVO's in the 1k range on a stock ECU. Was very please with the drivability and power. I made 477 on 93 and 596 on E85.
