I have an LS4 TB in the garage but not sure if i should use it. My concern is that i would actually lose horsepower. I have:

2.6
meth
header
magna flow cat back 2.5
ottp he
raw intake

i have a LS4 TB i dont think i "loss" any power from adding it lol

 

I heard someone lost 15 hp by adding it. I was just curious if anybody else found this to be true?

Thank you sir.

 

i was just in brighton....... ill hit you up again sometime when am there again

 

hey i know this is a dumb question but ls4 tb is that off the gto motor or is it off the 2.2 or 2.4 cobalt

 

Neither, it's from GM's transverse V8 (hence the LS4 Throttle Body name). Although I would imagine there would be other electrically driven throttle bodies from other GM V8s that might work.
