anybody here running custom tunes from kennedy(econo/race) for a stock tranny? what are your opinions? i just ordered mine and cant wait!!
Unless we got our wires crossed, you have the non race tuning coming that should be OK on the stock trans. No biggie, we can always upgrade as the need arises...stroke250;1577204; said:anybody here running custom tunes from kennedy(econo/race) for a stock tranny? what are your opinions? i just ordered mine and cant wait!!
Actually, it's only 50HP gain at 3100 RPM and 100HP gain at 3100 RPM. Peak HP still builds beyond 3100. The 100HP tune has been set up to deliver flat TQ curve at just over 600 lb/ft. If you'd lik ethe economy tune tamed down a bit I can do so. It has a nice TQ curve that tends to get a bit more aggressive at about 2400-2600 RPM.DmaxCC6spd;1577857; said:I only have a few miles on John's tunes, but I'm a happy customer. I ordered the econ and Tow tunes. I expected the econ tune to be a bit peppier than stock and the tow tune to feel really nice pulling a fully loaded trailer up hills. I had been running a TST Powermax on level 4. I was shocked when I discovered that I could burn the tires with the econ tune! I can't imagine what his race tune is like.
Overall the tunes are very smooth. Power comes on very quickly and the low RPM response and power is what I wanted.
John delivers again!
Your views on economy are the same as mine. Modify for performance and efficiency and if you can gain some economy, bonus. Your EGT's should stay in check without issue in most situations as I add boost where needed. I have guys towing with my Race tuning. That said, if you abuse it you can get things out of line in a hurry. Heck, a stock LLY can see 1500°f+. For exhaust, I'dd say full system to get real benefits. I tune for 80-100RWHP with a stock trans. I try to run a flat curve around 600-650 lb/ft TQ at the wheels. How well the trans deals with this can vary, but in most cases it is safe. Under acheiving trans and over acheiving engines could mess with this strategymandersonle;1578219; said:Thats fine, the economy tune is just a bonus in my mind. What I am really interested in is the tow tune. I am located just across the border in MN and am planning on doing some business with you later this spring.
I was wondering if you could address my questions regarding the two tune:
"I pull a 34' 5ver that weighs approx. 9k. Will the tow tune make the engine run hotter than the factory tune? What about EGTs? If I add a 4" cat back in addition to the tow tune what would the estimated HP and TQ number be and at what rpm?"
This is my KD Custom switchable tuning. I do offer a complimentary tune with EFI Live purchase just like other vendors. Those tunes are designed to show the basic strategy behind tuning the Dmax so the user can see what is being done and refine them from there.misley;1578255; said:Are these tunes being discussed ones that were purchased and installed by Kennedy or are they the EFI Live tunes that you get if you purchase EFI from Kennedy?
From what I've read there's a difference between the two. Also can you switch between the two tunes (whichever they may be) similar to the dsp2 switch?
Don't get me wrong, I like the Econ tune, I was just shocked at the power it made! The race tunes must be sick (or maybe I've been without a powerful performance car for too long!)Kennedy;1577994; said:Actually, it's only 50HP gain at 3100 RPM and 100HP gain at 3100 RPM.
