Problems with tune after install mods (CAI, TB, Plenum, etc)

[anieriz]

Hi everyone,

I have a problem with my mustang and i wanted to know your opinion about the correct parameters for some sections at Diablosport U7146.

I own a Mustang GT 2001 (manual) with the following mods: CAI (SR Performance), Underdrive Pulleys (SR Preformance), TB/Plenum Combo (Professional Products), Gears Set 3.55 (Ford), Mufflers Flowmaster 40 Series, Diablosport U7146 and Tires 20 inch (NEXEN Rear Tires 285/30/20, Front Tires 255/35/20 ). All the mods were installed 3 days ago over a well-working stock platform.
The diablosport Predator U7146 software version is v.9r07b. The Gasoline with Higher Octane available at my country is 95.
After installed all the parts i connected the diablosport and choosen the option 'Modify Stock Tune' and changed the following parameters:

(it is the last config that worked fine to me but still not good)

*Axle Ratio = 3.54
*Tires revs per mile = 753
*Traction = off
*Idle rpm
---> Manual = 870
*Rev and Speed Limits
---> Speed limiter Off MPH = Off
---> Speed limiter ON MPH = Off
*Spark Advance
---> Spark Advance 2k-4k = 1
---> Spark Advance 4k-7k = 1
*WOT Fuel
---> Open Loop Fuel 2k-4k = -12
---> Open Loop Fuel 4k-7k = -6

what is the problem at this moment ?

The machine performs very well moving forward. The problem is when it starts to decelerate. A series of explosions occur in the exhaust and i want to fix it.

Thanks in advance for your help.
