Back in August we reached out to all of you to submit the questions you’d like to have answered by the infamous John Heinricy. We got with John to get answers to your questions and posted the entire Q&A as a special treat to you, the GMTunerSource.com fan. Well after that feature was over and John had spent a little more seat time in the Stage 1-equipped Cobalt SS Turbo, we received some more questions from all of you and followed up with John to see what his long-term opinions and observations were of the kit. Mr. Heinricy was kind enough to give us his take, which we have exclusively after the break.
John Heinricy on GMPP Cobalt SS Turbo Stage 1 Kit (p/n 19212670):
"It is faster, I am turning better lap times"
"I have noticed more under steer"
"With the lower RPM Horsepower peak the need for short shifting is more noticeable on the track than on the street"
"I do get inside tire spin, I did not get before"
In case you’ve been living under a rock, the Stage 1 Kit is out right now. Just give your local GM dealership a call and let them know that you want part number 19212670 installed in your car right now! If you’re looking for a deal, CrateEngineDepot.com is running a special on all Stage 1 Kits that simply can’t be beat.
