Stillen Supercharger reliabiity

irondoc

So the car is home and the SC works. Last dyno pull on the Dynojet produced 395 WHP and 286 lb-ft of torque at 68.5 degrees on what Stillen calls a "safe" tune.
Pre-install run with a stock set up adding only a Nismo exhaust ran at
275 WHP and 231 lb-ft torque at 68 degrees.

This amounts to a gain of 120 WHP at a cost of $8200 total with installation.

According to the mechanic at IPS Motorsports the Blizzaks (275/35R19 Bridgestone Blizzak LM-60) are heavy at 30lbs and produce a significant limitation on power of as much as 2% in comparison to a performance summer tire such as my Continental ExtremeContact DW 285/35ZR19
99Y SL at 27 lbs. That would put output at roughly 402WHP with the summer tires.
Maybe some one can weigh in whether they agree with this theory.
The car drives properly. Not overly loud under the hood though I can hear the turbine whine over 4K and the power really hits at about 5K.

My only issue now is the tune is off just a bit in that when I coast down from over 30mph with the clutch in or the car in neutral it stalls every time.

I will work with Stillen this coming week to get a new tune changing only the idle settings and reflash the ECU myself.
