Well, I got my PHP remote programmer yesterday. I ordered it on May 29th and received it on June 12th. Not to bad of a wait time if you ask me especially for the price.
I had decided that I would just go straight to the Atlas 40 before sending it back. I probably will not try the Tow tune and I won't try the Atlas 80 or Hercules because I'm still on the TTY head bolts.
Also, I guess I should note that my truck is completely stock other than the fact that I am running the blue FP spring, my tires are 265/70R17's instead of the 275/70/R18's that originally came on it (which makes RPM's higher at all speeds), rear gears are 3.73LS's and I'm running a ScanGauge 2 and a Glow Shift 3-in-1 (Boost/EGT/FP) gauge. Other than that she's all stock.
This truck has always had a little turbo lag since I purchased it in February of this year. And, I've never been able to spin the tires on dry pavement unless I power brake it into a hard right turn from a stop. I live above 5000 feet and so I'm sure that's not helping at all.
None-the-less I was hoping for some change after I installed the Atlas 40 program and I got it. I am 100% impressed with it now. It feels like a whole new truck. And I have to agree with most who say it feels like you are driving a gasser. You are using a lot less pedal to get it going from a stop and you use a lot less pedal to keep it cruising on the highway. It's just so weird how it feels, so unlike how it used to be.
I had to take it for a test drive last night after I got off work and noticed right away pulling out of my driveway that it seemed like there was very little if any turbo lag. It felt a lot less lethargic. And so I took it easy on the highway while on my way to get some fuel, wanting to listen and just make sure everything was going to be fine. And I noticed that I was having to use a lot less pedal to keep it at 75mph but was finding that I was hitting 85mph much more easily now and having to watch myself.
Coming out of the fuel station I romped on it just a little bit (not real hard but not soft either) and it actually barked the tires. I couldn't believe it. I had a grin from ear to ear! At that point I was sold and couldn't even wonder what it would be like to install an SCT with some custom tunes.
There is one caveat though and that is heat. I have a long, low grade 75mph climb just before the exit for my town. The hill is probably 2-3 miles long and I know that the truck hits a little over 800F on the EGT during that climb. But, with the Atlas 40 it was a solid 900F all the way up. With a 4" turbo back I'm hoping I will be able to knock that back down to 800F.
I am hugely impressed with PHP and their Atlas 40 FICM tune. It's a true night and day difference in the truck. Two very big
Cliff notes: PHP, Atlas 40, holy crap new truck!
