Ok I know this has been beat to death. But bare with me. I've been researching the difference between cobb and perrin stage 2 OTS maps. Now I've searched every thread on every forum I can find about this subject. And everyone seems about 50/50 split. I'm ordering a downpipe and intake but I'm not sure which companies map to go with. Obviously I need to pick one before I can order certain parts(namely the intake)
Those of you who have had those companies maps. Are the Perrin maps truly more powerful as I've read? If we're talking about a ~5-8 hp difference then I don't care either way I guess. But some people make it out to be that perrin OTS maps make like 20+ more whp and are smoother than a cobb stage 2. This doesn't seem possible to me but I have to ask before dropping $600 on an AP.
Also on a related note. I was all for getting the cobb downpipe. But then I noticed that it necks down to 2.5" where it connects to the catback. Will this pose any lost hp when using a stage 2 OTS map? I am going to hook whatever downpipe up to the stock catback until I can afford the 1g most catbacks cost. Really like cobbs build quality but dunno about the 2.5" connection
