T25 lag?

[ExtraGoodness]

what up, guys? I just finished my SR swap a few days ago and its a pretty basic swap (FMIC & the 3 inch Isis straight pipe with dual 4 inch tips). So I've been taking some pulls around the block and it runs perfectly fine except when i go into 3rd. Shit goes mad slow and you can hear the turbo spooling really loud but the speed is bearly increasing when I floor it. the only way it'll be normal is if i redline 2nd and go into 3rd flooring it.
:hide: anyone ever have this problem? could it be a boost leak, bad turbo, or what? thanks in advance.

Do a boost leak test, both pre-and post throttle body

Boost leak test is the first thing to do. What kind of boost control are you running? It's possible that the wastegate is getting stuck.

Check your baseline/CAS timing too.

How fast are you going when you shift into third?

I second that.

Check the CAS condition (splines not worn), and if it is set correctly.

Check fuel pump too.

In both cases the turbo is running bloody hot and will die if you dont fix these.

my speedometer is broken but its just a reg shift out of second at normal shifting speed. maybe like 30 mph.

thanks guys, i will check all of this right now!

Guys I got a quick question my SR seems to be lacking power. I'm think it's because I've got a leak somewhere and the main place right now is from the downpipe to the testpipe I can feel air coming from it when it put my hand near it.


Could this be the cause of my slow ass SR? I mean my boost gage is showing that it's at 7lbs however I'm not feeling shit.

Exhaust leak wouldnt cause your car to run crappy...not unless its before the O2 sensor and the ECU is trying to compensate for the reading at close loop, but that will be on light throttle and not affect your open loop/on the throttle.

Thank you kind sir, looks like I'm back to the drawing board.
