LY6coupe

ok guys, im still very new to lsx engine. so i have read tons of diff builds and forums on ls1tech. seem to me unlike the old sbc, no set up is the same. you can really get a good start,but there will be bumps lol.with that said i am trying to build an 2007 ly6. i have ordered the vvt delete kit from TS so i can get rid of vvt. (i have my reasons,lol.) i also bought a elderbrock l92 efi vic intake with the rails,85lbs fast injectors,elderbrock elbow, bbk db cable throttle body,will get a cam from patg soon. my question is there a wire harness that i could use with the 58x and have converted to db cable? if so, what pcm would be best? i have the e38 that came with the engine,would that be optimal? or would i have to buy one of the 24x to 58x converter boxes? or worst case,just change the wheel to 24x............................................... . thanks guys for all the great info you provide here on this site. most of our projects wouldnt even be possible.
