went down to dallas yesterday to get tuned by mark for turbotrix got most boost i got out the car on the way down was 20.5 and it was set for 21. i justhought it was l lil warm and didn't think about it. get the car on the dyno, first pull 16 lbs, next 14 next 17 so we take the car off let it cool of i check all the hose and we decide to to a pressure test and hear air coming out the throttle body.... mark said this was a common problem on 1g DS's but he never seen it on a evo. anyone know anything about this.? any help would be appreciated.

 

Chances are it is just the hose clamp holding the upper IC pipe to the throttlebody. Use a T-Bolt clamp and it won't leak. Hair spray also helps out.

 

nope its not that... it comes from the throttle body and when you tighten the throttle down it stops leaking. everyone thinks is the shaft the butterfly is bent or something. im gonna pull it off and look at it today

 

Keep us posted. (us = people with boost problems)

 

well i found my problem... leaking tb gasket..... got into boost at idle my friends sprayed some carb cleaner in it and we found the leak.. at the top of the tb. so tomorrow i'll order some new gaskets.

 

how to put load (boost) on idle?

 

^^ Not at idle Mabye he was on a dyno?
