I'm going to be doing putting a ft550 in my completely stock d15b7 as well. Currently building a css d16z6 but getting the ft550 first and playing with that stock. How you liking it now 4 months later?
Ive been battling with a misfire issue at high rpm which i believe is noise from the distributor rpm signal. Im going to be installing a delacruz trigger kit on the car this week and see if that resolves my issue. Overall ive really enjoyed the fueltech. Definitely glad i did the daily driver before my race car. Theres alot to learn. Should have an update video next week. The car has been swapped to a d16y8.
