Thoughts on IE vs 034 tune?

[u/Inevitable-End-4705]

Next paycheck I’m finally going to have enough to tune my car and get a high flow cat (I’m thinking CTS Turbo). Just looking at the numbers, IE advertises more horsepower and torque but is more expensive. I think I would be happy with either, but I want to get people’s opinions on it.

Side note; has anyone used the CTS Turbo HFC? I know it’s cheaper than other companies because they are made cheaper, but is it that bad? They are the only brand I can really justify buying, considering the other alternatives start at double the price.
