i have a pretty built motor. 12:1 compression wiseco pistons, eagle rods, rev valve train, type r headers, skunk 2 stage 2 pro series cams, aem cam gears, stock intake manifold. 310cc precision injectors, 2.5 cat with n1 apexi exhaust, p28 chipped 93 octane.i took my car to get tuned and it didnt make any type of power, 150 hp and 105 tq, can someone please help me?....the tuner i went to said that the cams were too big and thats why im losing power and that i need to change my intake manifold and my headers. is this true? what kind of power am i suppose to be making?

high flow cat and exhaust? u should be making pretty good power. can u post a dyno?

 

im only making 150 hp and 105 tq, i have a 2.5 straigh with an apexi n1 exhaust

 

what type of power you think i should be making? the tuner said that i need to change my intake manifold and my headers to get power and that my cams are too big and thats why im not making power at all

 

yeah it certainly seems like there is something wrong. With the compression you are running what fuel are you using? What ECU?
You said that you are using the stock intake manifold, what size injectors, fuel rail?
A little bit more information is gonna be necessary before anyone is going to be able to make any type of informed recommendation as to possible solutions.

 

93 octane, 310 cc precision injectors, p28 chipped

 

anybody?

DAMN another member is making 144hp and 112 tq on a STOCK GSR !!!! Something isnt right .. u lost torque

 

i know something is wrong the motor is built

 

I'm sure the stock intake manifold and type-r header is definitely choking off some of the power... but i would still think u would make more than 150. Different tuner? lol

 

lol i went to 2 different guys, one couldnt even find the problem and said my motor wasnt built and i was making 114hp, then i went to another guy and now im at 150hp and he said that the headers and manifold were my problem

 

This is quite the interesting problem, have you done a leak-down and/or compression test? If you are getting blow-by from incorrectly pressed rings it would cause a major drop in power.

 

i did a compression test it was making 270

 

ya dude def. get a different int. mani. edelbrock makes a good one skunk 2 etc. and a different header

 

to big of cams would not be your problem with a 12:1 compression, they would just make more power at higher RPM. your tuner is a tard..
what kind of fuel pressure are running..
does your"tuner" do a sensor check, like check all your sensors.. take a runn over all your sensors and make sure they are in spec..

 

so what else could it be? what power am i suppose to be making?

 

please close thread

 

2.5in cat back?

 

You don't need an intake manifold, if you get an aftermarket manifold, you will see that 105ft-lbs diminish to like 95ft-lbs.

 

did you ever figure out your problem?

 

I just noticed the "please close thread" 4 years later? What's the point in wasting your time?

 

x2 at least let us know what happened if your going to bother trying to close the thread 4 yrs later.

 

lol i know 4 years later wtf is that?

 

lol dude your leaving all of us wondering what the hell was the problem ive never heard of someone suffering from that much power with internal work done

 

4 years later because I am selling the car now and i searched the threads i had opened sorry. it was the jumper harness that was screwed up and I went to a different tuner with skunk 2 stage 1 pro cams.
