I once purchased the Track Heat Intake from Trick Flow and the Motor lost HP and some Torque on the Dyno in comparision to the GT-40.
Called TF and they said it was not the proper Intake for my Setup, and I got allot of run around from Them about it. I was very mad at them at the time, becuase I spent a long time on the phone with them explaining every detail about my motor and they told me exactly what intake I needed from them and then for them to turn around and tell me they told me it was the wrong recommendation! So even tho they admitted they made an error in recommendation, they wouldn't lift a finger to fix it. Their big issue was that they wouldn't take it back because I had it port matched to my heads. So, like many customers it comes down to someone eating a loss, and it ended up being me the customer. They could have taken it back from me and refunded my money and then sold a fully ported intake to someone else at a discounted price. Instead, that is what I had to, I sold the TF eventually and bought a Down's Box Upper and it was the right one
Anyway, I have done business with TF on other things, but for whatever reason, my number came up to have a bad customer/product experience with them with the intake, leaving me wondering if this was the same company I had done business with when I originally bought the product. Talk about a Jekyll and Hyde switch.
I still like their products, and am extremely happy with their Street Heat Heads I bought years ago. Overall a quality company but even the best of intentions can go terribly wrong.
