IDP X vs GH SRL

Has anyone tried the extreme x and the SRL+ and seen a difference between the 2?

Extreme X is about the only tune I haven't tried so I can't give comparison but the srl+ is very smooth and linear with no light switch effect. It also shifts very well, I really like Matt's tranny tuning.

Ya that's what I'm running now the SRL and it dominates, but I spoke to idp and they said the X is like 20 more hp than the extreme race. If someone has tried different race tunes please chime in

my setup is way different, but ill take my gearhead file over my extreme x any day. The gearhead file shifts way better in my truck.

Gearhead also has srlX now that is hotter than srl+, I have it but haven't run it yet. Right now my strongest tune is looney wild track. But I will be swapping it out for winter because of slick roads, when it lights my truck gets a little scary, just need something a little more predictable on ice.

Eric's Xtreme X is faster and more powerful than any tune I have ran. However, I think the SRL(+, ++, and X) are like TSD's SPD and run smoother. I guess it comes down to what you want. Both are GREAT tunes.

I have both. My truck came with Idp's. I prefer Matt's tunes over Eric's. it seems with Eric's the shift points are off because the rev limiter always in. My vote goes to gear head!
