hi guys i have had an fp green installed for over 3 monthes now. when it was first installed i was making nice tq number but ever since the torque hasnt been there. has anyone had this problem before hopefully its just another boost leak,or a bad wastegate

 

have you checked for boost leaks? just like you said, that could be a big problem.
what are your power mods?

 

What to do when cars start losing power, it is an age old question.

Leaks, either charge air or turbine inlet air, either will cost power. Of course there are the "normal items" such as dirty air filter, aging cat converter, aging plugs and my favorite, hot summer weather.

BOOST ON!

my car has no cat,new plus,coils,wires im going to do another boost leak test my power mods are tbe,255fp,680cc ,hks dlii,264 hkscams,flashed,injen piping kit,aps bov,exedy twin disn,

 

Definitely do a boost leak test. If no leaks are found, check the wastegate for proper adjustment. Are you noticing late spool?

 

Boost leak test man. Also what is your basis that your losing torque? Have you gone on a dyno or is it a seat of your pants type thing? Also how hot is it where you are? I see you have the green, but no mention of a upgraded FMIC. While its not a necessity if it is indeed hotter now that may be the cause of loss of power and slower spool (air not as dense).

 

Are you relying on the butt dyno for your power loss data or another kind of dyno?

 

yes i was a victim or horrible tq at the bottom end, once i got two step colder plugs and the DLI2 tq went from 360 to 400 just like that......with a few adjustments to map of course.....

are you spitting or misfiring at all during your pulls??

 

oh and yes are you using a dyno to come to this conclusion, cause i would say mine dropped in tq a few days after my dyno pulls but i know its cause i got used to the power..........

we are fall victim to that problem........LOL

 

i have a larger fmic its weird car just doesnt have the ***** anymore

 

Boost leak test, tune, change in temp....false knock...a myriad of things are possible.

 

seat of the power feelings are tough to validate....

it's preffered to have have logged data to justify your claims.....

look at my m2 vs. s1 dj dyno compare to get 91 octane tq numbers.....your results may vary.

 

its not seat of power feeling before the car was making about 355-360 peak tq now its making 310 peak . in low rpms from 3-5k im losing 90 whp from what it used to be . im going from what my car made 3 monthes ago to now

 

still running the same boost??

check for leaks??

other than that give the car a overall inspection to ensure everything is good and tight

 

yes car is still running the same boost level
