I have a 98 LS1 and I was looking to replace the stock cam with a Comp Cam .522/0.529 Dur @.50; 212/218; 114. I also plan to replace the stock intake with a LSX. Do I need a PCM programmer to get the most out of this package?

Clipper

use the search man, there's an incredible amount of information on the topic in the internal engine section. But to answer your question, to get the most out of it, yes, you'll need a tune.

The car should be very driveable w/o a tune since the cam is relativley small, but to get the most power you will need a tune. Personally I would get the tune.

(No you will not need a tune for that cam, but a tune will always squeez the most out of any mod) Well, the good news is, you can go bigger, get everything you want, and all for basically the same price. Go to thunderracing, and check out their "old man" cam. It's ENTIRELY stealth, but will increase power over the entire band, and is larger than what you're looking at now. Instead of getting the F.A.S.T. LSX intake manifold, go for the regular Z06 manifold (the LSX's are more for engines that are more heavily modified). W/ the money you save from that, get yourself a tune, and you'll be just about squared away. Remember too, if you're going to pay for a good tune, you could go as large as the TR 224/224 for good power, stock drivability, and Cali emisions legal. Just food for thought. Also, take clippers advice, and run a few searches. We'll all help you out, but you'll be able to ask more specific questions if you do your homework on the search button first. And Welcome to the site.

Thats a puni cam, why not get something a little larger? The big ones cost the same as the little ones. Any cam you get, you should get a tune to get a little bit more power out. Some cams require tuning for the car to even run worth a damn.

a comp 216/220 .535 on a 114 is a great little cam! good torque but lacks a little upstairs.... but if you want a stock like power band thats a great choice!

if you want a little more up top and can stand to loose 5 peak tq than a comp...
222/224 .566/.568 114 just a hair less TQ but pulls a lot better up top....
at 6000rpm its still climbing!

but look around! and YES get a real dyno tune done with LS1 edit!

M6HuggerSS

comps 216/220 makes a little more torque than the 222/224
but the 222/224 makes a alot more peak power!

im going with the 222/224 .566/.568 114
ill let you know how i like it....

there is a good comparo in POPULAR HOTRODDING testing 3 diff COMP CAMS on a new LS1 on an engine dyno... though it had headers, elec. water pump, accufab TB...

basline was 407hp 409tq ( note all runs ended @ 6200 rpm...which means the last 2 cams were still making power @ redline! i guess the 222 cam would have hit 455hp @ 6500 and the 228 would have hit 470 @ 6800 rpm.)

first cam was a SMALL 212/218 .522/.529 114 lsa
numbers went to 439hp 426tq ... made good torque and good hp...very solid gains.
and a near stock curve...nice looking graph.

second was a MEDIUM 222/224 .566/.568 112 lsa
numbers went to 450hp 422tq...made over 10 more peak hp and only lost 4 tq to the last cam... power band was about 500 rpm higher... very nice graph! this the cam i will probly get! good numbers and it will probly pass CA smog!

third was a BIG 228/230 .571/.573 112 lsa
numbers were 455hp 421tq...if revved to 7000 it would have made 465 or so...not much tq gain over stock and less than the small cam! but this would be a good racing only cam with ported heads!

so out of the 3 i say the MEDIUM cam won! had just as much TQ as the small cam and more than the big cam...it also made awsome peak power and did give a good 1500-6500 power band....it will be an awsome daily driver with ported heads!

I was thinking of going with a bigger Cam but it would require more engine mod than the one I chose. Just experimenting right now. knowing myself I will change later.

BirdMan(LS1)

I seen a similar or same article which compared three comp cam -vs- 4 different intakes. It also show the dyno result for each combination. With the combo I chose i should get at leat 439 hp.

Another question. Swapping out your MAF from stock, does this make a difference as far as hp / trq ? Or is it so little you will never tell?

I've heard of that one going both ways. Probably not worth the money IMO (in my oppinion). When you get to an engine build that is starving for more air, then go for the MAF.

Are you looking for a completely stealth camshaft? We've been running the 220/220 xer camshaft on a 115 for our sleeper setups. Are you staying with cats or going off road y pipe? With cats in place you'll be able to run a larger camshaft & not hear it The xer lobes feature .581 lift so you still get the aggressive lift even with a sleeper cam Shoot me a IM if you guys want me to post my dyno results from my wife's sleeper camshaft install. We basically picked up about 30rwhp from the sleeper camshaft

With any cam change you'll probably be best off with a tune. We've seen really small camshafts still cause surging. If you decide you need tuning for the cam install drop me a IM! We offer custom mail order tunes for $250

How about a big 237 242 camshaft & we forget about being a sleeper!!! LOL
