I've been thinking about getting my car tune. But I'm not really knowledgeable when it comes to it. I need more source input.

Thanks for your help

My setup now:

03' Track coupe
- Intake
- Plenum Spacer
- Headers
- Test Pipes
- Full Exhaust

Mods Soon:

- Clutch & Flywheel
- Pulley kit
- Cobb Access Port
- Kinetix Upper Plenum

Mods Later:

- TT

 

I'd tune it now.....you are likely running pretty lean with those breather mods. I wouldn't use the cobb though. Also, skip the kinetix plenum if you already have a spacer.

 

Agreed with the above. The clutch/flywheel and pulleys won't do anything to your car where you will need a retune. I did some dyno testing on that matter. I would also forget about the kinetix plenum and do it when you do your TT. The spacer will show you better gains when staying with boltons.

I'm guessing that when you say tune now, you mean with the cobb? Because it would be a waste of money to buy Osiris then change out to Cobb.

 

Im running an identical setup to yours and my AFR was WHACK. I would def get a tune.

 

Do you guys mind if I ask you to supply the usual hp/tq "to the wheels" with my setup? Like where is my number with these setup?

Also the usual rwhp gain after tune.

Thanks for all inputs!

Yeah I know clutch and flywheel + pulley kit won't help gain power, but it will help my drivetrain decrease its load a bit. RPM would be more responsive as well.

 

Here are the numbers i got when i did the same install as yours. My components lists are almost the same as yours except that I have an MREV2 but it doesn't add anything to topend based on the other dynos out there for a nonrevup.

stock: 210/184
headers, testipes, catback + fuel correction: 225/200 (15/16 gains)
intake, spacer, lower plenum: 235/203 (10/3 gains)
osiris tune: 248/216 (13/13 gains)
new flywheel, pulley, rotors: 250/224 (2/8 gains)

Net gains are 40wph/40wtq. I lightened my drivetrain quite a bit and my rotors by 10lbs.

HTH.

 

Thanks for the input, it gives me an idea of where I'm at. The flywheel + pulley has good gains so should I wait until I get my clutch + flywheel +pulley kit before tune?

What do you think of open source tune?

 

How much does it add anyways?

 

I think it was something like 2-3whp and wtq at the topend, but the reason i bought it was for the 5-9wtq at the lowend (<3500rpm). So if you are looking for peak power, then this mod is probably not worth it for you.

 

i'm pretty certain that most of gains from the lightened components are due to the rotors rather then the flywheel + pulley. I think if you are going to get those items in the near future then might as well wait and get a tune with everything on, just in case if it does alter your afr. If i knew i was going to get those at the time then i would have waited until the end to get a tune.

I have no experience on the open source tune, i'd be more concerned whether or not the person tuning your car knows how to use it. Any tuning software or equipment can be bad if somewhat is not versed in it.

 

The overall number doesn't mean a whole because all dyno's are calibrated differently.
Bolt-ons and tune gained 42/31 on my car.

 

ahhh.. gotta love ricer math.

 

How is it ricer math?

 

haha ricer math

 

Since most of the guys that claim ricer math actually have no clue what they are talking about nor do they have any backing about any of their knowledge. Here are the results. And please tell me where the ricer math. If you don't know don't post or don't pretend to know, you are wasting people's time. Or either it's because you are the ricer wishing that the mods you have are better.

OP here are the results for your benefit.
with headers, test pipes and exhaust

with intake, spacer, and mrev2

with tune

with new clutch/flywheel, rotors, pulleys. (lower one is with 20" rims vs 18" rims)

 

By the way forgot to mention to you that after installation of each mods (first two dynos), my car was making less power. For those, we had to do a minor fuel correction to get some meaningful results. But you can see that on top of those fuel correction, the tune helped a lot.

 

I am seeing 209.7 to 249.3 horsepower with bolt-ons plus tune? That is impressive.

 

Yeah, the net gains were around 40whp/40wtq, I think that is about average comparing to others that I've seen with similar mods. The car's power is definitely better when I driveit.

For some reason that comes out to ricer math, which i'm not sure how. Perhaps the dyno is not as accurate as those guys' butt dyno above.

 

Nexx gets confused if he has to respond with anything outside of "HR is faster" give him a break lol.

 

Haha, but you know what's funny though. Eventhough those two guys are wrong, they still won't admit it and probably still think that they are right to this point. It's funny how primitive and narrow minded some human beings are.
