Re: Dyno #'s after a CAM tune.

Thank you,

I mean hell, if he knew something was actually wrong with the cats have some damn compassion charge the guy $75 for 4 pulls and tell him to fix it and bring it back..

Then he can make $475 total and actually have a good running car and a real happy customer..

That IS if theres actually something wrong with the cats

I'll take that bet, and up the ante by 10x. If you honestly believe a mail order tune will outperform a dyno tune, you're naive.

Besides, there's more to a tune than peak number internet bragging rights.

How can complain and say he only picked up 11rwhp. Maybe the tune he had on his car wasn't that far off. So when it was tuned perfectly he only gained 11rwhp. Thats like saying every car that comes in will gain 15rwhp off a dyno tune. You can only gain as much hp as your set up will allow you, Its not like the guy can keep tuning it and tuning it up to 400rwhp. I don't know the "Milkman" personally but he did try to help me when i had a low hp problem and i respect and thank him for it.

Re: Dyno #'s after a CAM tune.

What if some monkey is the one doing the dyno tuning?

Perfect tune my butt.. I would buy that if the car actually made decent power but it looks about 20-30rwhp short to me!

11rwhp is what you get MAYBE out of a totally stock car..

No he can't keep tuning and tuning, but we all thought that his numbers were a bit on the low side, even with shorties. There are people without a cam or even rockers making his power that have a mailorder tune, which leaves quite a bit to be wanted.

As mentioned above, if there was a problem with the cats, the guy should have cut tuning off a bit early and had him come back after everything was replaced; this way he could optimize total output from the car instead of trying to squeeze water from a rock.

Re: Dyno #'s after a CAM tune.

not to be mean or disrespectful to the initial poster, but I laid down more torque with my stock tune, stock cam, without 1.6 rockers, than he did with a cam/rockers/dynotune. yes i do have LT's, but I wouldnt imagine that would be the only difference.

That is true. He probably should of gone home but i guess we don't know that part of the story. If he knew his cats were bad he shouldn't of even tried it on the dyno. Oh well its not that big of a deal. I've heard that this Milkman guy is one of the best. I would take my car to him if he was close enough. I hope you at least got some datalogs so you can try to find out exactly where your problem is at, if its not the cats.

I don't mean any disrespect to the 'milkman,' but for $400 you better believe Id have my car back to his dyno for another tune after I fixed the cat problem. Hell, I wouldnt have left in the first place if I had only gained 11rwhp on a $400 tune. I would have asked for a reduction in price OR a promise of at least 2 more dyno runs/tune after all repairs were made.

$400 may not be a lot to some of you, but to a poor college kid like me, it definitely is!

Re: Dyno #'s after a CAM tune.

He shouldn't have been responsible for taking the car off.. The milkman should have!

You Heard, everyone has heard.. and I believe it to be from people who are getting over charged for work and wanting to validate the money spent.

Reevaluate wether he is "the man" or not by the dyno sheets you have seen here.

I've been irratated with this since i saw some 18 year old kid leave his shop with a 13.9 AFR with probally over $400 less in his pocket

Re: Dyno #'s after a CAM tune.

To begin with, the 305 isn't that big of a cam and without heads, the numbers he is getting with shorties are about right, in my opinon.

Also, even though it was stated that the former owner had installed a hpp program, since it should be a OBD11 PCM, the owner mostly likely removed the program before selling it (since the programmer itself becomes, for the most part) unusable if it still retains the car's program I.e., the car probablly didn't have ANY after market tuning prior to the dyno tune.

If you were to read all at threads since this site was started, regarding dyno results with various mods, I believe that you would come reasonabley close to what one could expect given planned mods. Meaning that with a mild cam and shorties and CAI, you are unlikely, even with a tune to get more than 315-325 RWHP. With heads, depending on the DO, and LTs you can add a few more ponies, but without a bigger cam, I wouldn't be willing to bet that he would see more than 350 anyway. JMHO

Re: Dyno #'s after a CAM tune.

if thats so why did my hotcammed 93 Z car do 333/343rwhp with edelbrock shorties, SLP CAI, and a hotcam kit? that was threw an automatic on WERX's dyno.

I think we all agree his numbers where low

Re: Dyno #'s after a CAM tune.

Jeff is right good. I oringinly had my head/cam setup tuned by someone else in northern VA and it sucked. took it to jeff and my car was mouch smoother... got rid of alot of cam surge.

$400 for 11rwhp aint bad...
and considering its a tune on a stock car... thats even better.

Re: Dyno #'s after a CAM tune.

Maybe it was a mustang dyno??? However those would acually be really good numbers for a mustang dyno lol.... I just think the thing needs a good pair of headers.

Re: Dyno #'s after a CAM tune.

Flechette: don't know how to respond that. Given the norm that your 93 would probably put down between 230-240 RWHP through an A4 stock, I am surprised that you gained nearly 100 RWHP with a Hotcam, CAI and shortie 1 /58 headers and untuned. JMHO
