Dammit Charlie Posted July 9, 2014 Report Share Posted July 9, 2014 Check your plugs? They can tell you a lot about what's going on in your engine. I was having a similar issue with my Cobalt SS. 4 new plugs and she's running like a snail on redbull. Quote Link to comment Share on other sites More sharing options...
boostin901 Posted July 9, 2014 Author Report Share Posted July 9, 2014 The car only has 20k on it ...wasn't sure if opening it up with an sri and bov if that would help Quote Link to comment Share on other sites More sharing options...
Second Gen Posted July 9, 2014 Report Share Posted July 9, 2014 Similar issues with my old RX7 and it was a manifold leak.. Exhaust is critical for Turbo (Wastegate / BOV is part of that system) Quote Link to comment Share on other sites More sharing options...
TTQ B4U Posted July 9, 2014 Report Share Posted July 9, 2014 The car only has 20k on it ...wasn't sure if opening it up with an sri and bov if that would help Have you had it since early on or is this a new to you car? BOV won't help other than sound. Stock ones can leak. Start there test wise. Also the MS3 runs in a recirculation mode not venting out. Switching that will cause issues. Getting bad turbo lag unless over 3600 rpm any suggestions on how to fix the issue..2013 mazdaspeed3:fuckyeah: In addition to the above I ask because by the factory tune the cars are crippled boost wise in first and second gear.

Cordell Posted July 9, 2014 Report Share Posted July 9, 2014 The factory wide band O2 sensor causes funny things like that, wasn't uncommon to see when I worked at Mazda. Unplug it and see if it goes away. Are you out of warranty? Quote Link to comment Share on other sites More sharing options...

boostin901 Posted July 9, 2014 Author Report Share Posted July 9, 2014 Yes the car is new to me only 1000 miles since I've owned it. ...the most common time when it happens is 4th or 5th gear below 3k it was to basically stutter spool Quote Link to comment Share on other sites More sharing options...
caseyctsv Posted July 10, 2014 Report Share Posted July 10, 2014 So you are saying it has no power in 4th or 5th gear under 3k? Quote Link to comment Share on other sites More sharing options...
SRTurbo04 Posted July 10, 2014 Report Share Posted July 10, 2014 So you are saying it has no power in 4th or 5th gear under 3k? If he is saying that then the easy way to fix this is down shift....or get a motor with more power. ... Not sure if this is a serious post or not, if thats the case ^ Quote Link to comment Share on other sites More sharing options...

boostin901 Posted July 10, 2014 Author Report Share Posted July 10, 2014 I'm saying in lower gears above 3 grand it sputter spools but then smooths out at higher boost ...and in 4th or 5th when I'm going 70mph or more it does the same thing when I step into it Quote Link to comment Share on other sites More sharing options...

Not sure if this is a serious post or not, if thats the case ^ MS3's have plenty of power/torque. You shouldn't however push the gas pedal down under 3k in 4th or 5th; you absolutely need to downshift. The car moves into boost at about 2,900rpm. On the highway the good part is in 6th at 72mph you're right at about 3k rpm wise thus passing in 6th doesn't really require a shift. If you want to really move past someone, just take it to 5th. If you want to sound like a bat out of hell passing, drop to fourth and power shift into 5th. Quote Link to comment Share on other sites More sharing options...
TTQ B4U Posted July 11, 2014 Report Share Posted July 11, 2014 I'm saying in lower gears above 3 grand it sputter spools but then smooths out at higher boost ...and in 4th or 5th when I'm going 70mph or more it does the same thing when I step into it at 70mph you're likely at 3,500 rpm. 4th you're well into the 4's. If it's sputtering into the 3's and 4s rpm wise, you need to have someone look at it. Side question.....do you know if the previous owner tried to flash a bad tune on it? Check the potential modification points and the program that's flashed onto it. I use a very mild tune on mine but can easily flash back to stock. Will bump it up to a more aggressive tune once I add a down pipe and higher capacity fuel pump to support things. I'm in no hurry though.

boostin901 Posted July 11, 2014 Author Report Share Posted July 11, 2014 Maybe a dumb question but I have never seen it before I found a wire that was tucked away in a round clip to my mere and into my fuse box and then I don't know where it went after that but the end up by the mere had a phone jack cable end on it any ideas what that was for Quote Link to comment Share on other sites More sharing options...
