Will the LS1’s over here are tuned different than the US cars, I guess they are designed to even operate on leaded fuel, it doesn’t say USE LEADED FUEL ONLY on the gauge cluster nor the fuel cap or any where on the car and have only 2 O2’s instead of 4. The ones we get in Middle East are GCC spec. I’ll pull some readings when I get HP Tuners.
