Hey guys, finally looking to wake up my 3.5L Ecoboost. I'm getting really tired of the sluggish throttle response and want some more towing power for hauling the boat.
Can anyone recommend a solid company for custom tunes? I already have an intake and exhaust done, but I need a good tune to tie it all together safely.
You definitely need to check out 5 Star Tuning. I've been running their 87 tow/perf and 93 performance tunes for a while now and the difference is night and day.
The shifts are way smoother and that annoying factory throttle lag is completely gone.
