Modded guys and performance minded advice

[StaLL1oN]

Have you guys seen feedback or dynos on the Pacesetter long tubes for an 03 5.7?

I just put a set on (ceramic) along with the matching Y pipe and I seriously feel like its slower than it was prior.

Also any input on the SC 3815.. With the 91 tune my truck doesn't feel any faster or run any better than the 87 tune.

Here's my setup

03' Ram 4x4 5.7

Pacesetter 70C2211, Pacesetter Y pipe matching
S&B cold air intake oiled filter
Superchips 3815 on 91 tune running 93 octane
85mm ported TB.

I felt a noticeable difference when I had my LT's put on. I had the whole exhaust done with it too. Wish I could help you more!

Its all good brother, merry Christmas!... I'll get some 0-60 times after Christmas and post them let everyone decide

On yours though when your parked and revving on it does it let you rev passed 4k?

I can rev mine to like 5k let off but if i try to hit it again while rpms are above 4k it kind of chokes out and won't do it until below 4k again.

Merry Christmas to you too brotha!

The revving thing is in the tune. You should be able to adjust the rev limiter to change how high it revs in Park using your tuner.

Also if you got your tune before the LT's you would have to revise it to get full effect.
And the wierd revving thing is normal for these electric throttle bodies.

Rev limit in park is for safety since there is absolutely no reason to rev above 4 grand in park. That is one parameter I left alone on my tune. I didn't want to take the chance of something going wrong, my engine over rev, & self grenade, I don't have that kind of money to take chances.

When I first had mine installed it kinda felt sluggy but after a couple hundred miles I defy noticed a difference. I went from full stock exhaust to the pacesetters

I'm on a Superchips canned tune, do you mean take it back to stock and then re program the 91 performance tune?

There is a break in period, you will feel/hear them more and more. Also, it's probably a good idea to unplug your battery for a couple hours.

Ok, what exactly would that be doing?

I dont know superchips, but are there not adjustable parameters you can play with when you add mods?
It has also been stated on here that diablosport doesnt play well with the 03s, likes to fry the abs module i do believe.

If redtruck va checks in he can tell you all about it!

Any idea how long the break period is lol?

 

[Hemi8073]

there is no break in period for headers…… maybe a few miles of driving for the cpm to adjust fuel trims but thats about it

 

[Hemi8073]

are you really feeling no gains from them???

 

[StaLL1oN]

No noticeable gains lol...starting to think I shouldve went with something other than pacesetter?

 

[Hemi8073]

I've never heard of anyone not gaining from headers, should have done some before and after 0-60's

it takes a bit for the pcm to learn new flow characteristics..maybe a 100 miles (or 2..), it surprised me one day because it was all of a sudden... also, if you do rest pcm you need to drive it like you stole it so that pcm learns quicker

..I've been runnin my coated pacesetter lt's for 9 years and over 200k miles..I likem...
