Best Hp = 258, best Tq = 324.
First 3 runs @19 psi. last 2 at 20-20.5 psi. Run 8 is the only one it did not break up on after 5000 rpm.
Bob Brady was on me to lean it out, and i did, but i like to move in small steps. There is more in the turbo, but i was up against some issues with erratic air flow signal at higher rpm, and afr that seems to jump rich when the duty cycle goes past 85%. I may be able to get around that by leaning it out, but with the air flow signal jumping around it is difficult to dial in the afr. I do not have a lot of tune time on the 2G mas, 2 secondary, re flashed afc Neo setup yet.
Mods at the time.
88 TSI 19c ported turbine housing and exhaust manifold. Marnel head, arp studs, factory head gasket, 7 to 1 compression Modified tep down pipe. Rob Kruger 2.5 exh with cat. Tep intercooler & otvc pipe. 2G mas, 2 Secondarys and bumped up fuel pressure. Tuned with reflashed afc Neo (program version 1.104). Rear 9s. Lightened flywheel & Bosch "350" fuel pump. Bse and ac delete. Innovated X16 wideband and two SSI4 logger boxes.
I did have about %40 unleaded race gas in it, but some braver souls have done similar #'s on pump.
First run of the day. (run 5)
