Cool Runnings asked what he will gain. I gave him testimonials as I can't tell him. I don't give much faith in them either BUT tuning can have very good effects on the way an engine performs. Factory tunes are very conservative and everyone knows that so gains are fairly easy. If someone knows tuning basics they can improve all the items I mentioned.

Uh, What?

It "CAN" but if you don't know what you are doing, you'd be lucky if you don't break something. We watched how nitrous CAN make power gains. In fact, he had it running like a raped ape till the engine died. Manifold was ice cold. He broke something real bad.

Simply put, aguilar92c4, as mentioned by HM2 would not, IMO, be considered a disinterested person since he is their vendor. OTOH, if you tested that chip against a couple of other "guess a tunes" and liked it, we could say you don't have an ax to grind.

Nitrous is a whole different ball game that I'm not getting into...Even good tuners tuning on a dyno can F' up nitrous builds... I'm talking gains on stock currently and many people have proven you can get great gains on modded engines with a "guess a tune" as you call it. Granted a mail order tune will never be spot on considering the tuner doesn't have instant access to all the readings but they certainly can get damn close. Again not all tuners are the same and some are not as good as others... clearly... just look at this thread...


That's your opinion but I know that most tuners take this quite seriously and it's not just a "I'll change this number ans see what it does" tune. If they don't care how the tune comes out how are they supposed to keep their business successful. There are not too many LT1 and earlier tuners around these days that are terrible. Most have gone by the wayside.

Not sure. I thought the C4 gains were minimal on stock? Yes, some are better than others which is why you will pay more for their work. IF the work you do is worth $20 an hour, you certainly wouldn't take $10. If you do, I suspect something is FUBARed.

Let me see if I can clarify. They may care about their work and do is conscientiously. That said, when all you have is a build sheet, you can estimate what is going on and write the program for it. I have seen that done on the dyno. The difference being that the dyno gives feedback and you can make adjustments and fine tune it in. I have seen several dyno tuners do that. Adjust till it goes up and back it off once it goes down to get the final tune. IF the tuner is doing that via datalogging, fair enough. If you are simply estimating what the car needs, I call it guessing.

I guess if you were going to do it, a guy with a shop dedicated to turning, with one dyno or more.. Who do it every, single, day.. Would probably be the best bet.

Maybe their experience could get them close?

aklim

You are right. How close do I have to be is the question. AFAIK, the closer to spec the better. I tend to be fussy so close does not work well if there is closer for a reasonable amount more.

I had Custom chips make one for my 93 C4. The car does accelerate faster. I also had code 32 removed and my fan temps lowered down to 190 degrees. Car runs much better!

aklim

How much faster? Did you do back to back runs? Dyno?

Update:

Custom chips is a complete scam. I made my order on August 8th and they stated that it was on its way. I have been asking for shipping details ever since and I get the same response. It is on its way.Here we are on October 25th and no results. Anybody claiming they received this product is probably the seller.

To the seller of this product who continually scams on this website. You have until the end of this week to send the adapter I paid for or I will turn you in for fraud. https://www.ic3.gov/default.aspx

I also suggest anybody else who was ripped off by this fake vendor to send in a complaint. I wonder how much $$$$ has been stolen.
