its not the computer that makes the difference, its the control module for the traction control, that, according to other members here, can be swapped out between 08/09 w/o other mods.

fair enough...but if you do DPthen you must do the rest of the exhaust...changing DP and leaving stock tail section of exhaust is like blowing through a straw that a big on top and small at exit...it might as well be small everywhere.

i asked one of the engineers about if ms1 would take away the full off function.." since it is a seperate computer it will not be effected.. " full off does turn of the tq limits.. but does not increase the psi of the turbo.. so say in 4th with stg 1 on a 08 you'll get 319tq before throttle pull.. on the same setup on a 09 you'll get the full bolt on amount .. say 330tq at the same boost level, but will not allow a overboost level. not pull the throttle because of the extra tq. If chevy can unlock there pcm so there is not a limit.. with that crappy p.o.s. tranny they installed on it.. why can't dodge?

This is the first I have heard of that. How come on the MS1 it lists its TQ limits? Looks like the TQ is limited on the ECU not a traction control module. Is there anyone that has proof of this with a dyno?

Here is the info about the MS1

Stage 1 Turbo Upgrade Kit Components

• P5155200 Mopar Performance Powertrain Control Module (Kit P5155175) (For vehicles built prior to January 15, 2008)
OR
• P5155201 Mopar Performance Powertrain Control Module (Kit P5155199) (For vehicles built after January 15, 2008)
• K6857152 Instruction Sheet

Recommended Upgrades:
• P5155071 Caliber SRT-4 Cat-Back Exhaust System
• 77070008 Caliber SRT-4 Cold Air Intake System

It is also recommended that the spark plugs be replaced before installing the Turbo Upgrade Kit. Use:
• ZFR5AP Spark Plugs Gapped to .031"
Stage 1 Turbo Upgrade Kit Feature Description
• Increased WOT boost.
To develop additional peak power and peak torque for the Stage 1 package, the boost was increased in all gears under wide-open throttle (WOT) conditions. The maximum torque limit has been increased to 245lb*ft in first gear and 300 lb*ft in second through sixth.
• Revised Throttle Pedal Calibration
The pedal response curve has been recalibrated for improved response and performance feel.

oops.. still gotta get plugs.. anyone know what type of plugs those are they reccomend?

BGP · 11-13-2009, 09:26 AM

I went with the iridium plugs,NGK I believe which I got from MPx. If you get these DON'T gap them with a regular spark plug gapper as you will damage this iridium tip. Turbo engines respond well to intake and exhaust..That's why the first mods that I personally did was the exhaust from the downpipe back and the intake...Then I went to a hard uppipe with a bov to help the turbo function better with any potential turbo lag. Then I went with the street motor mount inserts with traction bars to help reduce the torque steer with any future HP/torque increase mods along with lowering springs,bigger sway bars and a strut bar. Then I went with the MS1. Waiting this winter to do the stand-alone EMS along with either a bigger turbo package or the improved stock turbo package and fender braces I get info from some of my friends who have shops that specialize in turbocharged motors along with what I read here as well... I am trying to do well thought-out performance mods to have a well rounded performance car.

u can gut second kitty if you want.. it helps flow .. good for a few hp but nowhere near the amount as a full d/p. good way to pass a visual inspection, i think needswings is going to make a free flow upper pipe to replace so people like me can gut the second and .. well, you knokw.
