Talking Good Hint!!

Johnny,
That's one hell of a hint. LOL. Anyway, If you're just removing the SRT Intake and piggyback ecu, it should be pretty easy. Only one wire is actually cut and the SRT ecu wiring is spliced in. And the rest is just tapped onto, not cut. All you have to do is solder the one wire that was cut. You should not need to swap out the factory ecu. If you did, you will have other issues to deal with, like the imobilizer. I hope this helps.
How much boost are you planning on running, and is that an SRT or RMM s/c? Did you get the whole kit or are you having someone piece it together for you? Good luck.
Will

I believe TLW has been hinting at the RMM. If I had to venture a guess, I'd say this is morris' old kit.

there is also one more thing i want to say

i have said inthe past that the RMM supercharger bracket is all you need to bolt up a blower

i dont think that true anymore i think you need 3 pieces ...atleast

1.the bracket.

2. theidler pulley system

3.the spacer for the thermostat housing

it definitley is more invovlved
