** Update 9 / 18 / 07 ** Well went and finished getting tuned today took about 2 hours as we were still messing with air fuel a little trying to smooth it out more towards the last hour of tuning.

I have 17 runs of maps today lol so if anyone wants some datalogs or dyno charts let me know!
Just a little tidbit btw

I dynoed a month ago at 246HP and 316TQ I put the bypass on today and did a baseline dyno and did 266HP and forget the torque.. anyways TurboXS downpipe and race pipe added 20 horsepower.. just figured it was interesting ;)

Also did another dyno with bypass off after that and CPE Standback added 40HP after all tuning was done. Not bad for the price of an exhaust!



So I just installed it and everything was amazing. Instructions were above amazing and didn't take more than a couple hours. My only issue that I'm experiencing at the moment which I don't know why and I'll be calling Jordon to ask about this tomorrow. But While in 3rd gear if I shift early in 1st and 2nd then floor it in 3rd gear I experience I'm assuming fuel cut around 4k-4.5krpms. Never experienced fuel cut in this car before so not sure what it's like but the car literally lurches forward and definitely doesn't feel good... Anyones idea on if its fuel cut or something else would definitely be helpful. Again I'll be calling Jordon tomorrow to figure it out.. Also start sometimes seems to be difficult sometimes as in takes longer to start only a couple times so far.


All I have to say is the whole CPE team is awesome, I know its been said before but they are simply amazing. All my issues are fixed now that I had (due to elevation) which caused the car to run leaner than it should've. I'll include a few pics of the install and such don't mind me haven't shaved in a few days :P

Overall if your going to spend your money on any sort of product for your mazda go with CPE the quality and customer service is priceless compared to some of the other companies out there.

Definitely give CPE 10/10 on every scale.

This is an overlap from the same day the blue is very first run with bypass plug in. (so no engine mangement persay)

The red is after 17 dyno runs and finished product you can see the gains.



MODS - CPE Engine Management, ETS TMIC, HKS BOV, TurboXS Downpipe - race pipe, MS CAI and SU Engine mount.

I am going to try and Dyno this Sat. Don't think I will be doing any tuning as of yet as tuning cost some big bucks. Josh would love to see your maps if you don't mind?

By the way, are the racipes and your down pipe 3"?
 
Amazing, how difficult is it to hook up in the gears 1-3? I will definitely be purchasing the PnP model. How are u getting around the Fuel Cut-off? I swear I have felt it as well, 2 or 3 times, and all I have is the MS cai and TXS Hybrid BOV.
 
Actually 1-2nd is really torque limited compared to the other gears but in a good way I suppose... I can lock 1st and 2nd no problem except maybe a slight chirp sometimes.
 
I wounder what Turbo XS was smoking when they saw 50Tq/40whp gain with the Downpipe/racepipe combo. That is far from your 20whp you saw on the dyno.
 
I live pretty close to CPE. I might sneak up there and meet these guys in person. I haven't spent dime one with them and they treat me like a $1000 customer...because chances are, I'll end up being one. (upyours)

Well, whether you intend to spend money with us or not, you're more then welcome to stop by!! We'd love to show you exactly how we're so different from our competition. (wiggle)

And if you have any questions/comments that you've been dying to get off of your chest, be sure to bring those too :D
