Man, you're gonna hate this, but the Radium Surge Tank for the Z with 2x Ti BKS1001 will net you 1000lph+ AKA Stupid level fuel (2000whp+) for the same amount of $, but more clean setup. (In your stock tank)
I had a Stillen Gen 3 long-tube CAI, a Fast Intentions dual x-pipe cat back exhaust and then a dyno tune done on a Dynojet chassis dyno with Ecutek software. We got about 387 peak crankshaft(estimated) horsepower and a 15% uniform increase in torque across the whole rev range. It has made a big difference in how much more fun the car is to drive.
Im so used to my z that when i drove a mustang it was so weird that the shifter doesnt have any wiggle to the side or anything i kept pushing it left everytime i went to neutral like on the z lol
Nah I've had my Z paid off 2 years ago, been driving it for at least 2 years. Cops didn't fuck with me. Had one run in, barely going over the speed of an under cover cop. Lady thought I was trying to race her 🤣she let me go because she eventually realized she was reading into stuff that wasn't real
