This is my modification parts BBk long tube headers bbk xpip and flow master kit pack , Trick flow trick heat intake manifold with high-velocity intake ports and 75mm throttle body inlet,l range 1.500 RPM 7,200 RPM (BBK70mm throttle body , BBk AIR intake filter .Patriot heads stage 3, Competition Cams Xtreme Energy XE278AH -Intake Lift: 0.550 -Exhaust Lift: 0.550" Intake Duration @ .050": 242 degrees -Exhaust Duration @ .050": 246 degrees -LSA: 113 degrees -RPM range: 2200-6200 .TORQUE CONVERTER 3200 STALL, kit shift, ratio 390. ) 30lb fuel injectors,

i really need some one advice about this problem ?

 

that makes no sense. Is the tuner doing something wrong? Only thing i can think of is a bad tuner lol.

 

I heard the manifold can hurt power but I don't think it would be that bad...

 

Find another tuner...

 

Find another tuner. Or maybe the install on the heads and cams were bad. Idk, have a compression test done.

 

please note that i have check engin and the error shows the TORQUE CONVERTER and the OD drive it keeps blinking at long distance does that effect as i am planing to replace it to the stock to check it out

 

Yea, maybe your torque converter isnt locking right or something. i dont know though.

 

You have some issues there lol. Take it to someone else, and drive it as little as possible in the meantime.

 

new tuner. my stock 03 put down more than that

 

resolve the trans issue and follow the diagnostic troubleshooting tree for the code you are getting, the fact that the torque output is low on the dyno pull coupled with a trans code would indicate trans slippage or lack of lock up, so resolve the reason why the CEL is coming on and it may fix the low number issue on the dyno
