Ok i have another question. I hear that after putting my stock ls in my hatch and stock p75 ecu that i still have to get it tuned. is that true? sorry might be a dumb question. engine is in i just have to hook up wire, hoses, radiator, linkage, and axes basically. sorry i'm still learning about this stuff.

 

ok nevermind. the guy that told me that thought i was boosting it to since i have a turbo set. I know i need it tuned when i boost it tho. That will be a lil down the road tho after i do some engine work.
