anyone know the highest power made in a 4g64 powered Spyder GS? 227/288 is the highest i've seen in a spyder, but i've seen 337/353 on 20psi in a Galant (stock longblock) , same driver side timing belt 4g64 SOHC thats in the spyder gs. I want to push mine to see what she'll do on 18-20psi, making 232hp on 10psi atm. I'm having Boostin' Performance do the tune on the 4g63 Black Box ECU in my car. Engine was just rebuild and cleaned (removed "gunk" from oil journals in pistons, etc)

Crank is forged, rods are forged 4g63, pistons are oversized 4g63 (.060 over)

Auto Tranny until i go AWD, which i still might stay auto for the launches
