Jet Chip is out and ready for orders
On the same day running down a dragstrip 3 times, then installing a power adding device and running down the dragstrip again 3 times to me is far better proof that item works or doesn't work....and this can be done for <$50. Dynos cost >$160 around here.
OFF TOPIC THREAD JACK: how do you like your GMMP extroned and horned manifold
As for the GMPP Ext-honed manifold I couldn't give any rational feedback Vs original Manifold -- I had the GMPP Ext-honed manifold installed before I took delivery of my Cobalt SS/NA....to get the full car warranty on it.
