The old core - the one you had? - yes.
Rogue agree the new core is far more efficient and good for more. But given the price of a new setup, not many take the plunge!
Hence why I'm curious. So much "data" on here amounts to tribal knowledge. That can be both good and bad; if a company constantly develops a product, that knowledge can quickly fall into the "bad" category!
As Radtec make the cores from scratch they benefit from the latest advances. Same with their pre-rads. These aren't products that were designed and manufactured in the 90's and have been doing the rounds ever since. There are many folks using Radtec products at much higher than 400hp, they just don't drive MR2's.
Each to their own, not looking to start an argument either
