1/4" air line opening for 1 second (this represents your stock injectors)
3/8" air line opening for 1 second (this represents your RC injectors).

Both are spraying for 1 second as the ECU is programmed to do at a set air flow but the 3/8th is spraying way more in that 1 second time frame..

something like that. hah
Yeah I get the idea of it. But according to the rmm instructions the ecu would learn the injectors in 30 mins more or less. Thats why they warn that it might idle rough for the first 30 mins. But after that it should be able to handle it.
But regardless I'm gonna hook up the haltech and just get it tuned.

Also good news!!!. Messed around with it some more and no more cel light. Car feels strong at slow speeds. I can easily spin my tires at pretty much anytime in 2nd gear. I havent had a chance to get over 60 yet, too much traffic here atm. But car is feeling better, only thing is I do need to let off the gas for it to shift when ever i'm at wot. Guess I'm gonna need a valve body upgrade soon.
Another weird thing is it feels more like a turbo than an sc. I can tell when the boost hits, and thats when it starts to pull hard!!

3)I have a PI torque converter 2800 stall speed as well as a tranny intercooler installed. Its actually sandwiched inbetween the intercooler and the radiator. Seems to still be getting sufficient airflow though.
4) Yes the plugs I have are colder, (they were specifically purchased for use with the supercharger)
5) My haltech will be installed soon as well as a proper tune.

Oh yeah I might start a build thread as I have plenty of other parts to install.
Including my ppe headers which are sitting in my room

And I will post some proper videos once everything is running correctly. I do also have a video of how it sounds but I need to use a good camera as my videos were just shot on my blackberry. (sound sucks on blackberry)



Yes ups helped with the situation. But that was another huge hassle as well. Anyway I'm happy I have the kit now and I will get it running correctly.
I will also be joining this rare club in a couple of weeks myself hope its a smooth transition for me good luck ill be tuning in for tips!

If I had to guess, based on previous GS owners with the RMM SC, he will probably range anywhere from 360 - 390whp with his headers depending on the size of the pulley used (PSI of boost).

Congrats on the install.. sounds like it has been a long road.

I am interested to see the numbers the headers will add with boost..

Thanks, and yes it has been a long road. But it's finally done.
I'm curious about the headers too. I don't think any of the previous owners had headers when they had this kit installed, so im hoping the headers will add a good 20-30 hp. But who knows. I also have a tanabe medallian exhaust, so I hope to get right around 400whp. I'll post dyno numbers within the next 2 weeks

And to all those saying "I hope this works", don't worry IT WILL

Not sure how well I will do since its and 1/8 mile strip and it will be my first time running my car at a track. But regardless I will post videos. I'm guessing since I'm sc'd I might do better on a 1/4mile track.
