Accel Programmer/Tuner
I purchased this programmer about 6 months ago, and I'll say for the price it has been fantastic. It does not support custom tune files at the moment, or live data on my 2000 Dakota 4.7L. Which is fine I have software and a scanner for that. It does read and clear check engine codes, gets rid of the speed limiter, changes factory rev limiter, speedo correction, etc etc. It comes with multiple tune options ranging from economy, towing, and performance.
I have been on the 91oct performance tune since I bought it and here are the stats with GPS timing software via Torque.
2000 Quad Cab 2WD 4.7 with 45RFE and 3.55 gears
0-60mph: 7.5s
1/8 mile: 10.4s
1/4 mile: 16.3s
I am not claiming these hp/tq numbers to be 100% accurate
270.5HP @3600rpm
392ft lbs TQ @3600
****Not dyno numbers. But HP and TQ were also calculated off of GPS timing based off the gross factory weight of the truck, me in the seat, a full tank of gas, and the drag coefficient number of .471 ( I need to redo this as the actual drag coefficient of a 2000 is .49 and a 2005 is .471) These numbers are not set in stone, but the app is known to be relatively close to dyno numbers with some give or take. I do find it odd without using gear ratio as a factor as well though. The torque number does seem pretty high, but like I said, I am not actually claiming these to be true number.

I haven't done a stock tune pull, but I can flash back to factory and try it. I would assume probably 230hp 290ft lbs tq range. If I remember I think I'm on about 26 degrees timing WOT right now. Which I believe is moderate. I think, if only I remember correcrly, without other mods, 30 degrees advance at WOT is the max safe number. I could be wrong though. Not running rich besides at idle depending on outside temp. I think my IATs were over 100F when I did this as well.

Well looking on line I think the net hp was 235 and tq was 295.....
figure a 15% drivetrain loss would be about 200 hp and 250 tq. to the rear wheels.
I really find it hard to believe mopar left 70 rwhp and 143 tq on the table that a tune alone would have given.....
Not meaning to argue, but I would take the numbers as a grain of salt.....
At least compare to what the unit shows with a stock tune.
