both cams are great choices, the only thing i have heard about the FP4R's is that they are a pain to tune the idle. not sure if tuners have found a way to tune it without to many hassles. but either cam you chose will be a great choice. the lope on the FP4R's is prety aggressive at least from what i have heard/seen (videos) the S2's are a very popular choice as well.

 

I have heard the same thing about tuning the fp4rs. I know they are a great cam but for a daily driver it might not be the best idea. They are a great choice so don't be confused lol

 

lol i dont know where this hard to tune thing came form Jorge at JMS tuned my fp 4rs with no issues he did not send me a complaint once and you can see from the video my idle is great

 

You prefer your FP4rs? You havnt even seen your car since they have been installed...much less driven it. Your not comparing anything here...just posting to tell people you have the FP4r.

Anyways, onto some real feedback. A local switched the GSCs2 cams and picked up some really good power uptop on his 33r. I have s1, and if i ever upgrade, it will most likely be to s2.

 

I have heard that the fp4rs are hard to tune with the idle. I am leaning more towards s2s since thats what chad uses with his turbo.

 

haa your to funny so the shop has tuned my idle on the car and they have driven it and given me all feedback. Huh no difference think next time please. whether im behind the wheel or not i know everything thats going on down there. Also asked about the tuning the idle etc on top of that also i researched both fp cams and s2 cams before i made my selection . s2 are great cams as well pending your application as i have stated either cam will get the job done will good results

 

just get the gsc s2's with the bee hive valve springs. you will love them

 

S2's all the way. They idle close to stock and spool is just as good as stock. I gained 46whp going S2's with speed density over stock cams on the BBK turbo.

 

Mine do not idle like stock lol. Lopey town usa lol

 

Same here toxic but I like the slight lope to them they make some great mid power and tq.As far as the fp cams go for tuning your have to degree them a bit different then the s2's if you have a good shop installing them and tuner then you have no worries either way both great cams also note there a bit more pricey for the money I personally think it's not worth just my 2 cent.

 

i know you can tune out the lope but i like it, my car idles around 14.8-15.2 af and its outa control. lol

 

Aaron has mine idling pretty damn close to stock. It's all in the tune it seems.

 

whats your af at idle?

 

On E98 about where yours does
