Default Stage 1 with dual stage boost and wastegate

Ok I have a 2003 PT GT. I plan on getting the Mopar Stage 1 kit. But this isn't going to be enough for me. I'd also like a dual stage boost controller and I'll add a wastegate. I'll have a shop install the duel stage boost and wastegate and tune if for me just to be safe. So my main question is if I have the Stage 1 kit will this help the all around performance of the car vs the stock set up with a dual stage boost and wastegate setup?

You need to get the Mopar Stage 1 kit first, in your case 2003, the kit besides the PCM, you will get larger injectors, and that will give you a nice boost in power that you can build on, if you stay with the factory production PCM with the smaller injectors you will have less fuel and timing, also the stock PCM will give CEL light & codes if you boost past 15psi, where the Stage 1 over looks some of the sensors so you can play with more boost, 18 to 20 for the stock turbo, and a few other things.

You won't need a dual stage boost controller (dsbc) with the Stage 2 wga. Because of bad part throttle boost (PTB) you will need a dsbc with an AGP wga.

That is true, I forgot to mention that, I have my Stage 2 WGA sitting here to put in soon.

A few of us were at Cecil Dragway last Sat and with my mods listed below I held 15psi all the way through the traps. so hopefully with the S2 WGA I will be able to hold 17 to 18 through the 1/4 mile.

OK please excuse my stupidity. You all are actually teaching as I read this. What does DSBC and AGP wga stand for? Since it sounds like I'm going to need one kinda important I know what they are.

So then I'll also need a boost guage and it sounds like a fuel to air mixture guage wouldn't be a bad idea either.

DSBC = Dual Stage Boost Controller

A boost gauge is very important and an air/fuel gauge is a good thing to have.

AGP wga is a brand name wastegate.

I sounds like the Mopar Stage 2 wastegate is the way to go and not worry much about drive ability. Can a Mopar stage 3 wastegate be installed or is that over kill and asking for trouble?

I may be wrong, but from the pictures in the Mopar Performance catalogs I have, it looks to be made differently, as the Stage 3 exhaust manifold is different. I have also never heard of anybody using the Stage 3 WGA on a PT, except the very few that have converted the Stage 3 turbo & manifold to the PT.

Dream4,

Just curious, what was 1/4 mile times/speed?

have you ever had your PT "bog", like backfire?

Thanks,

Mike

I am still pretty much at Stock '05 Stage 1 levels, but my best run so far was last Nov. at Cecil County Drag Way was a 14.634 @ 96.03 mph with a crappy 60 foot time of 2.224. This is with a 3600 lb convertible. (almost 3900 lbs with me in it)

So a 3240 lb. 4 door sedan
PT with the same mods should do about 14.3xx, about .10 faster for every 100lb less weight.

I have never had a back fire or bog, it pulls smooth & hard all the way to red line, 6240 rpm. If you have this kind of problem, could have a plug or wire problem, I had to change my stock plug wires only after 1000 miles when it was new due to a miss on hard accel.

You can also see my Dyno sheet on my Mods web page below in my signature area.
