I have a 2006 mazdaspeed6 BONE STOCK. Around 3500 to 4000 rpm the car hesitates and stalls almost as if the car is literally turning on and off. This hesitation and stalling however only happens when I floor it. I have also notice that when I drive with no air filter, the car does not hesitate...

This is a quick thread to give people an idea of what they can expect from these setups. If you would like to add something feel free to post your stuff. AlexL @alexwlwsn PTE 6062 Gen2DBB - Max Effort Ethanol Tune - JMF PI DavidM @JohnnyTightlips PTE 5862 JB - Max Effort Ethanol Tune -JMF PI...
