I reflashed multiple times with diff. intakes and they only messed up my fuel trims. I also changed my rpms each time i did it to see a difference in idle.

 

[high3at0209]

There's a difference in idle, I just don't feel the power everyone says the feel right away

 

[b e z]

You dont notice a difference in the power in the power band, as in it doesnt feel more constant all the way through?

 

[high3at0209]

I feel it exactly the seams as stock, but maybe its just me, im gona give my friend a ride a little later to see if he feels the difference

 

[b e z]

My friend noticed the difference when he rode right away so maybe it is something with us where we get used to the power of the car.

 

[high3at0209]

Perhaps, riding in my friends 800so whp porsche messed up ny sense of speed a while back

 

[b e z]

Haha that could have something to do with it

yea sense of speed is messed up, gave 3 friends rides who all have been in my car plenty of times, all had a smile on their face after and said its faster

Get a stopwatch. Feel is meaningless. Smother power delivery, even with a substantial bump up in power, can "feel" slower.

Might not be able to tell that way either, with respect. Traction issues in first and second gear, sometimes in third, can make it very difficult to get reliable, repeatable measure of change in engine power mods. Try WOT pulls in fourth gear from about 55 mph up to 100 mph. Start a stopwatch as the speedo needle hits 60 and stop it when it hits 100. This is very repeatable, very reliable and eliminates all the variables that get introduced when trying to launch a FWD car with little to no traction in the lower two gears. Make several pulls on the stock tune and several with the HT on the same day under the same conditions, being careful to avoid any heat soak issues. This will tell you whether any mod, including HT tune is improving engine performance.

thanks for the tips, much appreciated
from your signature i notice we pretty much have the same mods, do you recommend the step colder plugs?

^ Big difference is he has a downpipe there but no you dont need them. I think msms3 has said before he didnt really need step colder plugs himself but he went ahead and got them.

Short answer. At your mod level stock heat range should work fine. Might want to gap them down to .028 though. A little protection against possible boost interference with spark. I don't think I need the colder plugs and may be giving up a horsepower or two to get a little more protection against possible knock.

Just got my ht yesterday and install it. You can definately feel the power and im stock.

 

[oaklandopen]

With just an addition of an intake you will feel much much more

 

[Tyrdstorm]

Bah! They need to hurry and release a map for the 2012s. My HT is just sitting on the floor and my car goes untuned. (boom06)

 

[zoomzoomMSP]

thought i had already checked in for having a HT but i guess not. so ive got one had it for over 6 months and loving it!!

 

[rsvinylgraphics]

Got mine yesterday, installed it but haven't driven with it yet.
