What cam are you guys running and getting by without a tune?

[ttocs]

You can hope that you will not need it but it would just be smarter to plan ahead for it. I was happy to find a good local tuner that once I had the chip would put it on the dyno and burn a chip for $250.

I wouldnt suggest doing a cam without a tune,And without a tune and unless your doing heads you will most likely not even see any power gain,you might even lose power, When I had a cam with bolt ons and didnt do the heads and intake my car wasnt any faster then when it was just full bolt ons,It's not worth the money you might as well wait and do the heads cam intake all @ once.


The 3 cams that seem to be sn95 computer friendley are the smaller cams like a steed 19 cam, ford racing,B cam, Ford Racing E cam.

But if you realize you need a tune then you will regret not going all out and getting serious h/c/i

For the V6's every cam comp makes is the same price. No reason not to get the biggest one.

For the 5.0 they are all $306.

thanks guys my car is a 5.0 and I have a F 303 i'm wanting to run. I was told if I use a TFS stage 1 or a F cam i wouldn't need a tune at all.i'll be using a mildly ported cobra intake and refreshed iron GT40's . basicly a little better than stock set-up.see later on i'm going to add my turbo kit and I know then i'll HAVE to get a tune then but I was wanting to install my other parts and ride a little bit before hand.

Trust me whoever told you You dont need a tune running A F cam is a moron, I had F cam its a decent size cam its 2nd from the largest ford racing cam and it idles like complete shit with a tune nevermind without a tune lol

I'd never run a cam or cams with out a tune it's asking for trouble. Which is better? $400 for a tune or $2000+ when you blow your motor?

Idk about blowing a motor just from running a cam untuned, its not like it's a lot of boost. I never felt like my engine was in danger.

you're chancing it at WOT. If the fuel maps are left untuned the chance of a lean spike is highly probable and could significantly damage the motor with detonation.

if the motor is not running right you run the risk of hurting it.

the ONLY way that you can risk damaging the engine, even at WOT is if you have changed the injectors or MAF. All the cam does is open the valves at a different time. The MAF will pick up on any increases in airflow and will fuel accordingly.

The stock maps are also INCREDIBLY rich in their OL fueling.

hottwheels04 i have called the guy who has built my engines in the past for my fox cars and he said he's put ALOT of cams in 95 cars without tunes and he said he hasn't run into any issues with any he's done.(18 years) experience BTW.he said all of them both foxes and sn95 cars idle a little worse with a cam untl it warms up and he said thats NOT enough to have to get a tune.he also said that he's never had one lack power without a tune either.i'm gonna try it,he's never let me down before so i'm going on his word.when I do it i'll let you guys know if it need one or not.and a F cam ain't that bad in a car,it's little compared to what i've usend in stock 302's before.and YES when I do this i'll be changing heads,cam,intake,inj,meter,MAF,the whole 9 yards.

that would be the first mechanic I have heard of with a perfect record on sn's. NEVER needed a tune?! This dude needs a personal invite on here.....

There was one annoying thing I ran into running an F cam untuned. When I would reset the ecm it would run great for a few days, but as the computer started adjusting things it would start surging after first start up for a few minutes before settling into a stable idle and not run nearly as good. Buying a Quarterhorse and adjusting things really made the car much more bearable.

 

[OnyxCobra]

my car definitely lacked power pretune, most noticeable for normal driving was low rpm tq.

I agree. I certainly hope after a few guys running the same cam and similar setups telling you their experience will clear any confusion you may have as to whether or not to get a tune.

 

[ttocs]

I had the same problem that before the tune it was fine above 1700 rpms but under that it would buck and stall and sound like crap.

Exactly, fox cars with the a9L computer run better, but I personally have had 2 diff motors in my car and owned 2 diff 5.0 cars and just had a F cam and have had 3 diff cams and even with a tune the cars idle like shit, without a tune they would just want to stall esp a Ford racing F cam, and I personally have numbers "real" numbers on the dyno to prove a cam with stock heads is a waste of money,and yes I agree with him lol that guys needs an invite because sn95 cars computers hate cams lol

 

[BYEBYE2U]

we shall see i guess whether they like'em or not.i'm planning on doing it before long and i'll update this thread on whats going on..

 

[Mrstangerbanger]

I have been there and done that .. I have every bolt on you can do to a sn95 and trust me you will need a tune period..

The car might run great but will not make the power you want ..

I know for a fact that the car will not idle worth a shit without a tune running a F cam .. ( Good friend is running the exact cam )

But all we can do is tell you what we have all dealt with and try to help its your car..

Back when my car had the original 302, I had a Crane 2031 in it, ran it without a tune for 2 years and it wasn't too bad. Took some playing with the timing, IAC adjuster screw on the TB, etc. I have also heard the Steeda 19 will run ok without a tune.

I doubt you will be happy driving that F cam without getting the car tuned. You will have a lot of idle issues. I will tell you this, the day I forked out the cash for a tune I wondered why I waited so long. It's a night and day difference. Granted, by that time I had a lot more new parts on the car to make a tune worth doing.

If I were to do it again, I would have waited and did the cam along with heads and intake at the same time.

 

[g36 monkey]

You will not regret getting a tune. Promise you.


Not to mention you familiarize yourself with a good shop and they are more likely to cut you a deal on the next tune for the FI setup you are talking about.
