its kinda hard to explain but ill give it my best shot... i think my dv is bad or my tps needs to be adjusted not sure..

any way pretty much any gear if im in it hard and let off lightly not full release of the pedal .... the dv will dump and im not sure if the trottle is closing but the car bucks hard n almost throws me into the wheel... most of the time when that happens i look at the boost guage n its still showing im under boost ... i donno what it is but its a pain in the *** its not limp mode. i have a ko4 giac chip


is there some way to set the tps to relearn what full closed is ? or is it just something else?

 

since no one replied ill add more to it the car will spike at 20 and then level off at 13/14psi witch makes me think it may be a boost leak im building a tester ill try it out see what happens and get back to this post sooner or later

 

Sound's like a characteristic of a bad TPS but that will be the first i have heard of one going bad in this model and type.

 

What year? What DV?

 

Car is a 98 and the DV is this one I belive http://www.stratmosphere.com/hyperboost.htm

And if it was the tPS switch wouldn't I get a code on my generic reader... my damn vag light still doesn't connect to my car for some reason

 

ok so i made a boost leak tester and did some testing right off the bat found a leak... the hose that goes from the compressor to the n75 had a nice rip in it... also my dv was loose ok ez fix's i also have a small one some were by the intercooler i just cant find for the life of me... i fixed all but that one and now my car is actully slower lmao same psi tho

now b4 i did this i found this wierd but it was quite awsome pretty much full boost as soon as i hit the gas pedal now that i fixed it i actully have lag...

and also ill hit my 18-20psi then it will go down to 15 and bounce from 15-18-15-18 under full throttle is that cuz of the small intercooler leak ???
