ID1050 injectors
Lingenfelter Balancer with 10% overdrive pulley
TR7IX Iridium Spark Plugs.
Custom Dyno tune.
Stainless Power long tube headers

Would all this get me over the 600 rwhp mark? And what IF i didnt use long tube headers? would my gains be significantly lower?

Thanks in advance.

With an CAI I saw 559-580 depending on the type of Dyno, w/o the headers/plugs, less if you have an auto..
