Stock port GSL-SE with a stock S4 turbo and manifold. S5 NA intake. Haltech, 3" exhaust with cat, FMIC. Boost spikes to 10 as it comes on then settles to 8 and holds there till the power falls off. Never mind the a/f graph. The dyno's sensor is for crap.

are you useing a stock motor how much boost, did you do a rebuild

 

he said "Stock port GSL-SE with a stock S4 turbo and manifold" which one could safely assume that the motor is, indeed, stock. He then says "Boost spikes to 10 as it comes on then settles to 8 and holds there till the power falls off" which again, one could safely assume boost was spiking at 10 lbs and then dropping to 8 till redline.

 

Yes. Completely stock 140ish,000 mile GSL-SE engine.

 

Nice turbo upgrade! i bet she's pretty fast.

 

Wow, that is cool. Congrats, and nice numbers.
