OK I HAVE A 2002 WRX ...i have upgraded ecu up down pipe intake boost controller / 248 whp ....just got tunned and ....one day when driving hard i hit 2nd gear and heard a pop .....no tranny damage all gears are fine .....but when im in 5th gear on highway and get on it and let off car jerks alot on deceleration......also i heard a noise when i shut it off on the passenger side .....like a clunk clunk ........also heard another pop when hitting second hard ........SMOKED AN upgraded mustang GT WOO HOOO......anyone know anything please help TY

 

no one knows anything?

 

its not backfiring is it?

 

nope

 

up graded engine & tranny mounts would be nice, but may or may not fix the noise. any of the factory soft mounts should be changed anyway IMO.

 

I have Group-n engine and tanny mounts. Get 'em their worth it. WHile you at it, rear diff bushings tighten everything up, and stops that driveline clunk.

 

Yep i orderd some cusco engine/tranny mounts too. I'm doin 270whp/310tq and from 1...2....3....and sometimes 4....i can hear a really bad clunk/pop sound. It only happend after i got the car tuned to those numbers, so i figure it has to be the mounts.

 

ok ty guys ill get me some mounts!
