Good Ecu.. But Piggyback in General isnt a good idea, when your taking a car to the levels I am... With a Piggyback you can only go at pertcentages over standard values of the stock ECU. But when your running nearly 3 times the power of the stock ECU, piggyback is certainly not ideal! Standalone removes any stock maps and you can create a brand new map from scratch. Basically Im going to gain a much smoother driving car, and maybe even a lil more power at the same boost level! Unsure, Ricky is busy at the moment and Im not sure I want to do a pretty drastic change to the car before the biggest show of the year. Maybe/Maybe Not The listing on ebay was vague, but the seller did have 100% feedback and was very honest and good comms with me.. It looks to be in MINT condition tbh.. But paypal offer great security for buyers so if it dont work I sure as hell wont be out of pocket! Ino... Hence me clicking buy it now, with it being on ebay for less then 20minutes on Sunday Morning lolz
