Camshaft good or bad?

hey everyone, i have been on a mission to get the most out of this 4.0 engine and was thinking of doing headers and a camshaft, but i am not sure about either one and just wanted some input from you guys. I have to do the short tube headers cause thats what you are allowed to do in cali. I got the air aid cai and the flowmaster 40 series so far. I would like all suggestions good or bad just wanted to get everyones opinion, thanks everyone!

 

no aftermarket cams yet.... get the x-1 if u want the most of ur engine, or supercharge it

 

what is the x-1? and i have been thinking about putting the supercharger on it but that would have to be way down the road when i have the money to do so haha

 

here ya go, things bitching! http://www.urdusa.com/product_info....=1260518754&osCsid=iop62f2shmqm0n903j8cnu1025

 

have you or anyone you know gotten this?

 

i dont, but the guy that tuned my truck did and his redline is just ridiculous.... this thing is great, u can do so much with it

 

i see you have the URD MAF cal how is that?

 

best mod so far... it really gave me the ability to have advantage of all my afftermarket stuff, brought everything together.. before i did the maf i was running lean, but now im tuned and it pulls

 

so that should be something i should do to my truck right? and do you have the short tube headers?

 

if u have no mods the maf will give u 15 hp more than the stock engine, so with ur intake itll really bring it together once u tune it... yes i have short tube headers... the only reason i suggested the x-1 cuz u asked bout camshafts and the x-1 lets u adjust the cam timing

 

oh no i understand completely i just got sidetracked with your mods and wanted to know about them sorry about that. How do you like the headers?

 

no worries man i really like the headers, i think its better for the N/A engine, but alot of people will argue that... i had a reputable shop port them out and welded them to the cats... it really brought the tone deeper, i love the pulsing sound it makes when im goin slow

 

yeah i bet they are nice, did you remove the 2 cats or do you still have all 4? Have any sound clips? sweet lookin truck by the way.

 

thanks man! i kept my first 2 set of cats, and gutted out the rear two with the pipe-bomb y-pipe... heres a sound clip, sorry bout the quality

 

OMG that is the most beautiful sound i have ever heard haha that is amazing bro!

 

thanks man!!

I have been running the X-1 almost since it came out. The best performance mod I've done behind the supercharger.

I have put down higher trap speeds and 1/4 ET times then any XR (as of now, and to the best of my knowledge). And that's not to say that there aren't faster XRs out there, there is always somebody faster. I have seen trucks with my same mods plus more (minus the X-1) run almost 3-6mph slower in the 1/4.

So hands down, one of the best performance mods you can do.

 

yeah i am deffinetly going to look at that setup you have tacoskim that truck sounds soooo badass. Thanks for your guys input on this!
