7with no tuning but since I already upgraded to the ls7 maf... And ls2 tb at the time of install . it was a 11on a scale of 1-10. The sad part is you get used to the new power fairly quickly and u want more.

I'll have to find some pics but the ls4 im bottlenecks almost half of the inlet after the tb the ceiling of the intake is shallow as hell and compared to the crude ls1 intake, you can see why this is a essential mod.
