I'm debating the point of getting a full tune after bolt-ons. I'm not sure if I'm going to be doing a cam after these, and if I do it won't be till at least next year. I'll be getting it tuned with lid, SSRA, ported TB, smooth bellows, LS6 intake, !AIR, !EGR, QTP 1 3/4 race LT's and ORY with dual electric cutouts. I'll also have the Tb coolant bypass and a 160* stat.
My question is, what kind of power increase could I expect with a full tune with those mods? I'm guessing around 10 hp but I really have no idea. If someone else has experience with this or has had a tune with these types of mods before let me know. I'm trying to decide if it's worth the money.

i'd say up to 20hp...but it will get rid of codes and run better

yes, get it tuned, delete any codes, and enjoy. tuning isnt just for HP; better throttle response, increase gas mileage, better drive ability, ect are also benefits to tuning.

i would wager ~15rwhp.

[QUOTE=Ru2n00n3er]I'm debating the point of getting a full tune after bolt-ons. I think it would depend on how soon you would get a cam. Tuning is expensive.

$500 for a full dyno tune

Buy Hp tuners or LS1 edit and tune it yourself. Some of those bolt on you have is killing you gas mileage,spark plug life, O2 sensor life.

well what about all the mods in my sig...that wouldn't be hurting my would it

Not as bad as my 5.3 Stage 3 tea headed, 383 with a little Comp 244/114 bump stick hurts the gas mileage.


But hopefully you stuff was tuned as soon as you put those goodies in.

I should have worded that as killing those items for no rewards.

actually haha...it hasn't been tuned in 5 months...and is getting tuned tomorrow...the previos owner did most all of the work and never had it tuned...i think it ended up screwing the o2 sensors and or plugs up or something else...you got any ideas on what could be screwed up this is the thread https://ls1tech.com/forums/general-maintenance-repairs/293351-car-won-t-stay-running.html

Speed Inc. is $450 for a full tune. I found someone that will delete codes and such for free to help me out, so I was thinking that then a full tune at Speed would only cost $300. Their basic tune costs $150 so I thought that price would come off if you didn't need it. But it doesn't. So it'll still cost me $450 for a full tune.
But I would end up wanting to get it dynoed after the mods anyway, to see the power increase. That's ~$90, and a tune would help me get better gas mileage which would save me money. I need to decide.

I will say this with all honesty. If you can buy HPtuners and have half a brain you can tune your car yourself.Unless you have some mega turbo or superchager setup.

Don't flame me and don't be pissed at me for saying that but it true.

I have had lt1edit and tunercats from when I had a LT1 car and now I own LS1edit and EFIlive now that I have a LS1 car and HPTUners is SO MUCH EASYIER TO LEARN.

OK this is the simple version.Without a tune on a car with headers and a cam you O2 sensors are SCREWED(plugs too), plus the fact that your MAF may have taken a dump (put your car in limp home mode) has foulded your plugs and causing you problems too.

Now as to your transmission problem that could be something as simple as very low fluid(I dought it), but most likely something more trouble some(read expensive).

my buddy picked up 10hp / 15tq at g-force in houston on st. pattys day. his only mods were MTI lid, Kooks headers, catted y-pipe, and GMMG. timing was horrible but mike fixed it up right

i plan on getting a tune w/ my cam this summer. they have a lifetime tune program, so jason said what the heck and had it done last thursday.

Getting a tune sounds great but I don't think I can afford it right now. I have done a few mods since I bought it stock and I definitely think it needs to be tuned. Thanks for the input guys.

You will FEEL the difference with the tune. I gained 3hp and 11ft/lbs at 3000RPM!!! You are more than ready for a tune - you will love it. Change some shift points too

Ru2n00n3er

I really don't know if I want to mess with the shift points that much until I get a cam in it.

i think he meant if you were an automatic car

definatly dont want to be revvin past the stock limiter on stock valvesprings, plus you arent making anymore power up there anyway.

Yeah, that makes more sense.

The first tune with your car at a single shop should be $500 or so. After that the cost of a tune should be by the hour, or at a reduced cost. They need to charge that much for the first tune because the shops pay over $200 for the software licensing for each VIN#.

Stay with the same shop and tune after big mods. You will not run right or get the full benefits out of your mods without a tune.

Good LucK!!

I had JBA shorties, high-flow cats, LS1 intake 26# injectors, stock TB. Dyno'd 335/349. I dumped it all for a ported TB, LS6 intake, 28.8# injectors, ported MAC's, and ORY ... thought I had more power because I had made the swaps.

Got it re-tuned a couple of weeks after all the swapping and the first dyno run produced numbers of 317/346 ... with a few A/F tweaks and some good tuning skills, it made what's in my sig ... 360/370. This was my situation ... others here will have different results, IMO. BTW, my car will idle perfectly now. Mike at NLP did the tuning.

So, based on this experience, I would say go for a tune without a doubt ... just know your tuner and that they are reputable and have good equipment and know how to use it.
