Ever since my car went in the shop for some upgrades (E85 flex fuel kit install, bigger fuel pump, 3 in intakes, Z1 headers, and the tune to support these mods), my car didn't feel right. The transmission behaved very strangely, not reacting to shifts as crisply, and has some intermittent idle surge. I'm wondering if there's anyone in socal who can take a look at my car, as I suspect there may be an electrical issue. Thanks.
