yes I had them jack it up and thinking I have the strongest Map now they have ,and it pulls great until 2500 to 3000 when it cuts out and I do a quick( on and off the throttle), then it pulls hard again ,, now on sport mode which is a much lighter tune , no problems but it is much slower ! Perhaps I was just expecting too much from the AWD Kia ,, as mine only Dyno at 356.5 and all others show around 400 + , I was running off pump gas 94 to 98 octane when Tested ,, as I read earlier some have thought that they got better torque with only a muffler delete ,, I can say this as well as I gotten 550 fb torque and after the Jun Bl and Borla I ran 502 ft lbs but went from 320 hp to 356.5 whp AWD

both tests were however done on a Dyno Com almost the same as Mustang Dyno,,which they told me runs 15 % lower than a Dyno Jet
