So I'm looking to order a PCM for my car after I get all my new parts installed, and I don't know what to order. The PCM I am looking to order is the one off of intense-racing.com (INTENSEâ„¢ Powertrain Control Module). There are three different types though, for a 2000 3.8 engine. The first one is a 3.08, 3.42, and 3.23. I don't know which one to get. And also, to get it custom tuned for the parts I'm getting, I think I have to include it inside the Custom Box right? These are a list of the parts I'll have on my car soon, I don't know which ones I'd have to tune my PCM for.

K&N Cold Air Intake
2 1/2 Magnaflow full Piping with catback
Pacesetter Headers
Taylor ThunderVolt 8.2 Spark Plug Wires
NGK TR55-IX Iridium Spark Plugs
INTENSEâ„¢ Normally Aspirated 3800 Camshafts + JPP Single Timing
CompCams High Load Valvesprings
Comp Cams "OE R Series" Hydraulic Roller Lifters
INTENSEâ„¢ Cam Installation Kit (L36)
ATI 245mm Street/Strip Heavy Duty Torque Converters


Any help would be awesome.

 

Why are you changing the PCM? You cantune the existing PCM to handle all your mods.

 

Really? Well, another stupid question incoming. Where would I tune it at? Those mail in places?

 

Put all the mods in first, then either get the car dyno tuned (best way) or get a mail order tune. You tell them about all your mods and they will exchange your PCM for a tuned one. Try www.pcmforless.com, they now offertunes the 3800 PCM (OBDII)

 

Awesome, thanks. It doesn't matter when I get it tuned, right? I won't have to do it instantly or anything? And also.. how much hp do you think all these mods are going to add to the car? 20 to 25 maybe?
