We're seeing about 10-15rwhp gain with just a tune. I can post the dyno sheets for comparison - 93 octane, no dyno tricks (no ice, full exhaust, rear brakes connected, full street trim). And we have a load control dyno (as does ECS) so we can get repeatable results.

Man I should have checked back a little sooner. I personally never said I can get 30hp from every Z. I have been able to get those #'s without any tricks or dyno magic. Car may have just been in bad need of a good tune. Did a bone stock CTS V serveral months ago that picked up 28rwhp from just the tune with the customer standing there watching. Some cars can and will pick up a good amount of power from a tune. I've also done some that only picked up 5 to 10 rwhp. Regradless theres almost always some power and gas milage in a good tune.

Somebody made a comment earlier that i would be back and comment as to how nice Willie has been to my corvette and they were right. It rides like a champ....just wait for what we have in store in the not to distant future...and yes there will be pictures.
Its not a competiition on here guys, Willie is just the best, HONEST mechanic that lives 30 mins from me. MANY others can attest to that. To the one poster who made a negative comment about my being done with this issue I AM NOT DONE! I have found a great mechanic and i am sure that the same guy who posted the BS about my done with the issue will have something negative, immature about my choice of what is being done to my car.
Personally i care only what Willie knows is right from his years of experiences in corvettes.
You that made the negative comment about how i was done with this issue merely INSPIRED ME to build a vette that will make you drool...but judging from your IQ, you probably drool uncontrollably.
Thanks will for you EXPERT mechanic work and our "sleeper" will be in progress in a couple months...to hell with the critics.
Bump for Willie Wiggins Racing!!!

So no. +50 HP is not reasonably attainable from a dyno tune unless you want to run $8 a gallon race gas and rebuild your engine after every race.
As stated above if the car is stock don't bother. If you add CAI & LTs ,exhaust you will need to change the fuel/air mix to fully maximize the additional air flowing through the system that your computer can't fully adjust for. Hand helds aren't worth the money. Have it dyno tuned once you settle in on what mods.
Anybody who tells you they can tune you to +50hp gain is looking to get additional business from you since you'll be buying new pistons to replace the ones you burn a hole in.

ECS simply the best just check out the record books
no numbers played with there 
some people just want to hear some fictitious hp gains
just cant handle the truth, it is well known that some company's play fast and loose with dyno numbers

Again, no knock on ***** - sounds like a good guy and finding a mechanic like that is awesome. Don't know what I'd do without ECS close by. Just never heard of gains like that from a stocker tune.
I think my Z came in at 360 rwhp with headers, CAI, and a tune. Have the dyno sheet at home somewhere.Love eastern NC. Matter of fact as an avid surfer I have made plenty of trips to OBX. Maybe I'll get down there again for another surf session when the weather warms up. Have a good Vette buddy in VA Beach who just had his first baby that I'm overdue for a visit with.

I'll be the giant tool
In no way am I saying every car tuned will pick up 20-30rwhp, but it is possible on some cars. I've done some that only pick up 4-5rwhp and some that pick up more. It really just depends on the car. Normally a car from the factory be it Chevy or Ford or what ever it will be on the rich side. With a good tune to move the AFR closer to 14.7 at cruise and 12.8-13.0 at WOT you should see better fuel mileage and more HP. Then you can also play with the timing a little to optimize that as well.

I find it hard to believe you can pick up 50hp from a tune alone, especially on a stock motor. If anyone has the dyno readouts where they were able to do that, post em!! 20-25hp is probably the ragged edge of the tuning table. (stock)

Just wait till they see what we have brewing under the hood of my vette...of course then Willie...they naysayers will always retort with accusations and if God himself were to come back early...and tell them it was factual....they would find fault or try and pick apart the reality.
To the brother who is coming down this summer...i will take you by willie's shop and perhaps we can drag him to hooters and have a cold one or two....Cheers brothers,
There is nothing wrong with having a difference of an opinion...thats a four letter word called life....but bashing someone and calling them out on what they have PERSONALLY SEEN AND DONE....( i had an awesome tune with exceptional HP gain...so go ahead and call me a liar...I have thick skin)
Willie is an all around good guy, helluva hunter and an even better tuner and mechanic.

No doubt your friend is a good tuner, but 2 of the best tuners in the country have already posted the gains of what these cars do.

Just wondering.Urfubars car isn't a Z it's a regular C5. EG and the others are right the Z's tunes are normally closer to being right or to the edge than the standard C5's are. So the HP gains aren't normally as high as on the standard C5's. I've never looked at any of their tunes to see what they're doing. But if they're just PE rapping the fueling and adjusting the timing it's possible they're not getting the full potential from the tunes (not saying that's what they're doing). And I've never had a 50rwhp gain on any stock tune unless it was on a FI setup. But I've also never tuned a stock car with race fuel.

Sir, please reread my post.
I never said they were the best, but 2 "of" the best.
No need to start a war of words with consumers here, it will hurt your business in the long run. You forgot to recognize that I guessed you were a good tuner.
