Yes my 08 Malibu shows the Lutz influence he started. He has left people to continue these improvement with each and every model.
The Manual has a no lift shift. I have driven it and it works but you really feel like you are going to break something but the computer controls everything. I do fear missing a shift on the cable sifter. FWD shifters are always crap.
The Turbo upgrade is only two map sensors and a flash. It sets it to 290 HP and 315 FT LBS. The Solstice with the same kit can get up to 340 FT LBS with the stronger transmission. It really drives like a different car.
The auto was 235 in first and second gear with 250 in third and fourth. The upgrade makes it 290/315 in all gears.
MPG went up 1-2 MPG too.
I hope they offer a similar kit for the new Camaro as it can add some real HP and torque if you are ok with Premium Required ratings.
