Again, I just don't see the point. All the changes you made to the tune could have been easily replicated by tuning the chip.

I'm not saying what you are doing isn't a neat idea because it is, but advertising it as a means to increase horse power beyond the capabilities of the stock ECM really isn't true. I'm afraid that those who don't really know what you are talking about are going to by your product based on the assumption that it has tuning capacity beyond the stock ECM. While there are some functions of the OBD2+ system that aren't available in the OBD1 cars, the things that make power (fuel and timing) are equally adjustable in both systems. My car is a 91 vette with a stock ECM tuned by me on my dynojet 224. There's not 5 more HP in the tune, regardless of tuning system. If you really believe that your product can produce more HP on my car, then I have an arrangement that I'd like to propose. I'll buy a system from you, bring my car to you for the install and tuning, and I just want to be there for the before and after dyno numbers. If you can pick up 5 RWHP anywhere in the tune, I'll buy 10 of your systems and carry them in my shop. If not, you can keep you system, re-install my stock stuff, pay for the gas and hotel, stop advertising it on here, and we'll call it even.

My dyno experience (probably not as great as yours, but significant) has been that a 12.9 as measured with a tail pipe probe is close to 12.3 or so if you were to measure at the header. Beyond that, even if you were seeing a true 12.9 at the motor, I'd bet a weeks pay that just about any mild, NA, small block chevy would make more power .5 of a point leaner. Most mild small blocks that I've tuned would run, without detonation or knock, at WOT, all the way up to a little leaner than 14.5 or so. However, most of the time they quit making more power at 13.5 or so; so there isn't any reason to run them that lean. I'm kind of rambling, but at any rate my point is that telling someone that 12.9 is perfect isn't really 100% accurate either.

Maybe I'm missing the point, and I hate to sound like a big meanie head, but so far it really looks to me like you are preying on the ignorance of the crowd here when it comes to tuning these cars. The only benefit I see to your system is that you don't burn chips, and whether or not that is an actual benefit is up for debate. Chips are cheaper, burn faster, and can be tuned in real time. Your set up uses a flash style ECM that minutes instead of seconds to upload tunes to, can't be tuned in real time, uses tuning software that is more expensive, a PCM that is WORTHLESS if you hang a tune or have a computer problem while uploading, and comes with all the headaches associated with a PCM swap.

Again, I apologize for coming off like a bad guy, but I just don't see the point in the product you are offering. Try not to take offense.
