It’s a 2013 grand Cherokee set 8 6.4l
Hello so I am wanting to buy a tune.
I do have hp tuners
I just installed a 797 performance cam it’s a killer bee stage 3.5l
It’s there full kit
Vvt lock out
Btr valve springs
Push rods
Upgraded hell cat lifters
High volume oil pump
Ngk spark plugs
I do have a x pipe
Has a aftermarket cold air intake
New timing chain etc
Right now after install you can start it it’ll run for like 3 seconds then die. And I knows it due to the tuning
Was seeing if you could create a custom tune for this application?
Before hand was just a base hp tune installed
Turned off MDs and the awd so it’s rwd
I do have a hp tuner.
Wasn’t sure if it’s something you could write for me and I upload?
