Gutted cat?
Still have that AFM?
What's your boost level?
I turned my SDL up around half a turn around 18 months ago, been running great @ 13.5psi. Looks like we're up around 30hp/30tq over stock, not bad at all considering it was free to do.
I prefer to keep my stuff simple, not really interested in going for an IC at this point, since it seems this power level is pretty safe long term. If it was low cost, fairly easy, and did not induce excess lag I would consider for sure.
