440whp on stock z31 AFM

[enjoyrth]

I think I currently hold the record for most power on the stock AFM so I figured I would post up here, since I am using nistune, and let people discuss. Here is the dyno graph and the nistune datalog. I am using the Z31_VG30_256_E_86-89 adr. file and have attached the bin file I am using.

[Timbo_021]

Did you need to modify or bypass the afm at all? i cant figure out how you get such a low voltage reading, mine maxes out at around 12psi at 4000rpm..

[FlawleZ]

And I believe I've made the most torque on the stock Z31 MAF.




I'm installing ported heads, cams, gutted plenum, etc. this weekend. I'll do some datalogging after the fact and see where my voltage stands on high boost.

[Curbsquirrel]

this is a long shot, but anybody have any idea what other specs of enjoyrth setup is with this tune? what size injecters in this tune?

[FlawleZ]

I don't remember off the top of my head but enjoyrth no longer holds the most power in the stock AFM. I made 545 RWHP and 540 RWTQ through the stock MAF last year.
