i burnt the num 1 piston in the gti-r motor running 20psi of boost being chased by a viper on the highway. this was before i upgraded to walbro 255l/hr fuel pump. i then got weisco forged pistons now with more fuel, i still burnt the num 1 piston. i know the number one cyl runs leaner/hotter than the rest because of the intake manifold shape.

any solutions or suggestions for this?
