LOL, you are right, I forgot that I went back to the Katech cnc stock one. Probably would swap out the MSD to the ported stock one but am too lazy (broke the new engine in NA).

I've been having part throttle tip-in very low RPM drivability issues for years now, at some point I must have switched to a ported one to fix it (it did not). The fix was actually putting primary cats on (LT or factory header). So you need to either source an early shipment metal line with silicone transition, or do like me and get another TB (or stock) as it add no HP. Here is a pic of the metal piping.

No back to my original question if you don't mind, can you drive the car 42 to 45 MPH in 5th with no issues? I can but only with primary cats.
