you only gained 3whp/6wtrq with the Ecutek tune? the 16whp/3wtrq over your baseline with the headers is nice to see. I'd venture down that road in the future. My only concern is fitment on the X models.

those are pretty good gains, congrats! I'm curious what you will gain from e85 when you go down that road. I may get there before you, I'm planning on doing the e85 switch in November.

Yep I didn't make much either with UPREV.. but ECUTEK is way better there is 0 dead pedal feel anywhere..the throttle is so responsive you touch the gas and go

yeah I wont be E85 till next year seeing I had to spend 600 to get new high flow because the Z1 ones were so poorly made..they didn't have anything I liked in stock and were charging a arm and leg to overnight them to me..
Really looking for that sheet :/

I don't think anyone has done a dyno after changing gears..you don't lose power the power band just shift's with the gears..
If I was to switch back to stock gears I would probably be around 330whp or more..

I made less power with my gears, it has to do with the load values, the 3.3 gears put more load on the engine so dyno numbers will be higher. he would probably be around 330 ish whp like he said. seb explained it to me last time my car was on his dyno. I have 3.90 gears and made 297whp with Takeda Cai and ark grip catback and ecutek.

only issue I'M having is the ECUTEK keeps throwing Speed Sensor codes.we have tried changing the Gear ratio and it doesn't do anything.don't know if its a bug in the software or something else.i reset them and the come right back soon as I turn the car off and on

I guess i learned something new today. I thought the power (well more so mid range power) wouldve been more due to the gears. esp. i thought the torque wouldve been higher... fine gains made by the headers... in for a sound clip.
