Based on what I've seen so far for 93 octane I think 460whp is a reasonable limit for a 58 and 500whp for a 6466. You can push them higher but it will become less consistent.
The 91 logs were perfect. D's #1 priority when tuning that kit was safety first, everything else second, including WHP numbers. Anytime he started seeing anything in a log he didn't like he backed it down until he was happy again. I will say, it seemed we were on the verge of a fueling crash at that point as HPFP was doing its normal dippy dance. This was before we modified the rail and the pump, after that we ended up with 67X no meth with some higher octane, and again logs that kept the most careful tuner I have ever worked with happy. The last thing we wanted was a hurt motor, we did at least 500 dyno pulls and another 500-1000 street pulls on that car at power levels varying from 550-725WHP, and he still daily drives the car 30 miles to work everyday without a hint of oil consumption. I have no doubt 600WHP can be had on 93 and the logs would be happy, this is just based on the experience we had tuning that first kit. I guess time will tell. "

But no question, auto switching to map 4 is very, very smart on your part. Most piggybacks couldn’t dream of that type of control and forethought, so credit where credit is due.
The DME does nothing at all. It just motors along like everything is fine with a 20:1 AFR. It doesn't even lower its load target. Bizarre.

Fuel trims work within a +34% range whether you are using a flash only tune, back end flash + JB4, or JB4 alone. With a JB4 in the mix the JB4 also can dynamically adjust the fuel pressure return to give another 30-40% of fuel trim room. "

With more fuel (upgraded HPFP) do you think those safe numbers would go up? "

Agreed, I don't think people that look at forums will actually buy DINAN, GIAC or now Renntech as first, there is a hassle of loading and unloading the tune, possible issues at dealership (maybe they will not be able to flash anything), and the price point is just not competitive when you consider JB4, BT cable and Cobb.

I don't doubt for a second your ability or PTF's. I'll believe it when I see it, and look forward to being proven wrong "

Right now I don't think it will happen without meth just as a fuel supplement. It's just a matter of fuel and big enough turbo to hit that on 93, but honestly I'd rather have a quicker spooling turbo and hit it with meth.

I'm still not sure whether or not I want to add race gas when I start tuning mine. I'm thinking start off with 93+meth and see how far that gets me then add in the race gas. That should provide some decent 93 numbers guys seem to keep asking for. "

Well now that is some good info. BTW Terry, I'll hopefully be tuning and dyno run next saturday. Going to do step by step dyno and road tuning, hopefully make a day of it assuming no issues. "

Buffalo Trace FTW! Now you need to find yourself a bottle of Blantons. Another great Buffalo Trace bourbon.

" [QUOTE=mjmarovi;559723]Ok...so power gains are similar to the JB4 or a Cobb with a protune. Maybe a little more power, but that's just being a little aggressive to get an extra ~20whp without doing other upgrades.
@Mike@Renntech I'll be honest that price does seem extremely high considering the Cobb Flash is $900 and offers a handheld that can be used for other features including datalogging. What do you offer in terms of re-flashing/tuning for additional upgrades and doing custom tuning depending on the location the vehicle will be used in?

See, basically what we are looking at is a the product of a very aggressive custom tune on one particular vehicle. So not only are those gains not going to be consistent using that same flash for other cars wherever they are, but it's not even safe or recommended.

I'm sure you have all of this thought out, but I am simply expressing concerns others would have as well. We just need more info, any new product especially from a company with a great reputation is going to catch some attention. The price really adds to attention because we would want to know what the advantages are. From the information you've posted so far...there are only disadvantages seen. The way it feels now is if I were to send my ECU in to you (major pain to do in itself plus additional costs) and have you flash it with some tune you got off of a test car, and send it back to me. How is that any better than buying a Cobb and using an Off The Shelf aggressive tune? Except for with the Cobb you can datalog some street pulls, and make adjustments yourself, or go to a Cobb pro-tuner in your area. Or, Pro-Tuning Freaks e-tune.

I'm sorry if it comes off as me being offensive, but I assure you I am doing nothing but trying to help and lay out all concerns and questions the majority of this platforms' users would have.

Thank you and looking forward to your response, "
