Gryphon 1st impressions

[jerodr]

I drove my mom's 07 fx2 most of the day today and there is so much difference in the amount of throttle needed to get the truck to respond from a dead stop. Here truck is stock so I know something funky is going on with mine. I thought my truck would be as good or better than hers after the gryphon but that is not the case.

I agree - I drove my truck quite a bit yesterday (had to pick up a mattress we just bought) and I paid extra attention to how it responded from a dead stop. There is NO lag at all, period! In a slow roll, if the transmission has shifted up into 2nd, there is a small delay while it shifts down to 1st, but I consider that a normal delay.

So, I'd talk to Bill about this. You may be able to PM him during this "closed for completing tunes" period and he may answer, or you could try emailing him or Corey. Since your case is not an "emergency", he may not be able to give it any attention until after they reopen for normal business.

Yeah that's pretty much how my mom's truck is. When I order my custom tunes I will speak to bill. It is definately not an emergency. I have good news though. I pulled my boat today from dallas to austin (250 miles) and what a difference in pulling power. I had it on level 2 and the downshifting for passing was so much better than stock. I also liked the fact that it would not hang in 3rd gear after coming over a hill like it does in stock mode. It will downshift when i hit the throttle and upshift just as quickly.

Yup! It's almost a crime (in my opinion) the way Ford tuned these things. That passing lag in the stock tune is really, literally, a killer, isn't it? I also noticed a pretty good gain in gas mileage (about 2mpg) when towing and using the "canned" tow tune. Bill's custom tune improved on that about 0.7mpg.

Yeah the stock tune is ridiculous. I averaged 15.5mpg which is definately the best mileage I have had pulling my boat. There wasn't hardly any wind today at all so it was a good "true" test of what it gets. I would say that it was around a 1.5-2mpg increase. What else did you notice about his towing tune over the canned tune if anything? Also I want to fill up with 93 octane and run the canned level 3 so do I need to advance the timing? If so how much?

If you fill with 93 octane and run a 91 octane canned tune, you should be able to advance the timing by 1 point in the custom options menu. (That's if your tank is FULL of 93 octane. If it's half 93 and half 87, you're actually using a blend that is close to 90 octane, so leave the timing alone till your tank is really full of the high priced stuff). Bill can, of course, write you a true 93 octane tune that will take full advantage of the stuff you put into the tank, because it tweaks more things than just timing.

If all you pull is a relatively light boat, 2000# or less (and it sounds like that's what you have), you can probably use any tune to pull it. But, Bill can write a custom tow tune for that weight too.

I think Bill's shifts were firmer than the canned tunes at WOT or near WOT. Beyond that, and the additional increase in fuel economy, I can't say I noticed anything.

That's what I figured about the timing...I'll give it a shot. I plan on getting the tow tune along with the other tunes very soon.
