who makes the best ECU performance chip for the 928? There's even one on eBay for $36 that claims 36HP increase. Anyone try this item out?![burnout](https://rennlist.com/forums/graemlins/burnout.gif)

I have a box full of those **** chips from when I either put in Sharktuner PEMS or put stock chips back in.

If you can't get the use of a Shark Tuner go with PorKens chips

Does it have the "Do It Yourself" manual transmission, or the superior "Fully Equipped by Porsche" Automatic Transmission?

For an S3: Porken's
For an 87+: OE Or Sharktuned (most-likely Porken's too; haven't tried them yet.)
I too have a box of crap after-market S4 chips.

Oops. My bad. I wasn't aware of general availability of his S4 chips.
