I did Z1 Intakes with velocity stack upgrades, 63 mm ported throttle bodies, z1 ported upper mani, fast intentions long tube headers, fast intentions exhaust, dynoed at 334 whp, 278 wtq (and my torque band starts early thanks to the headers).

I keep a lot of dyno data and results in a shared Google Drive file, you may enjoy looking over it. |
So Admin intake and uprev tune or Z1 intake with ecutek? Stock throttle bodies. I Really can't find anything that shows why Admin is worth the money but could be wrong. So many threads of back and fourth.
Also love that spreadsheet. Very interesting to see the different setups. Appreciate it
