I believe he ran into the same problem with the Hellion Twin Turbo setup as well. It's my assumption that once the stock cats are removed or replaced with a high-flow version will lower the boost and allow you to run better timing and make more power.
Also isn't it pretty common that FI vehicles run the risk of melting stock cats?
Really old post but if you google the topic it's pretty common

Yeah. Let headers and high flow cats seem to be the way. I suppose I will need to add that along with the cam and pistons. Now to find a brand and an option to work with the convertibles.
After the high flow cats and headers did the tuning problem disappear? Which headers did you go with?
