so I had him tune my Toyota MR2 with a 2grfe and he was very quick and responsive. it is utilizing a haltech ECU. I sent him over the current file on the car and when he sent me over the new file I verified that changes were made by comparing the maps. still currently working on it but I have high hopes.

Everything went smoothly from start to finish. The map turned out very good, with noticeable improvements, and works perfectly. He has solid technical knowledge and understands ECU tuning very well. I highly recommend him and would work with him again.
