Default YIKES PCM $400!?!

The only company that can make a PCM for my car is DHP. They said it would cost $275, + a $125 core charge. What is a core charge? Also, they said I could wire up a perform shift button since I don't have one. But do I really need one? Couldn't I just have it perform shift all the time or would that hurt the tranny and engine?

BTW- the Pcm would be a DHP version 1.0. Any good gains from that particular PCM?

The core is a deposit you make for your old pcm, when you send in your old one they send you your $125.
The performance shift would be a nice option but you could leave it performance all the time, it just raises your shift points and wont harm the tranny.

Oh, cool so I pay the $400 then when I get the PCM; I then send them my old one and get back the $125? Then it is only $275 which sounds good to me.

With the DHP, I wouldn't leave it on P-shift all the time. I always leave mine off until I need it. The shifts are very hard, and not pleasant for everyday driving. It'* great to have when you need them though. With the DHP, the line pressure increases significantly.

I really like mine. It really changed the way the car ran. My top end power increased greatly from it. Overall, the car is much faster with it.

I'd say wait until you have more mods definetly. a DHP for a 3.5 won't give you nearly the gains that one with a 3.4 or smaller, and other mods can give.

People have been pretty successful with a 3.5. The DHP will give you a gain with either a 3.4 or 3.5.

There'* a very marginal difference between the 3.5 and 3.4 pulley.

Not enough of a difference to spend more money on a new pulley when you prolly won't notice the difference.

I still say he ditches the sleeper sound and get'* a nice hi flow cat and muffler on that bitch.
