How much break in before pulley & chip?

[JerseySVT]

I picked up an 04 Cobra on Monday.:-D Love it. I brought it down to JDM and they slipped a Magnaflow cat-back on her for me the other day. Thanks for squeezing me into your busy schedule guys. Sounds much better now.:beer:

Anyway, I want to go ahead and do a chip, 2.8, x-pipe, headers, intake, Pro 5.0 shifter, and plugs. I only have about 300 miles on the car. Should I wait and break it in first? If so, how many miles should I put on it approx?

I think you are about ready. I'd give it a few hundred more miles, and start ordering.

There is really no need to wait. The engine is already broke in from the factory. Most, though, wait a month or so before going the pulley route. They usually start out with the typical exhaust/intake mods. I waited two months before going with a 2.90 pulley and chip. Sounds like you want to go for the throat sooner than later. LOL! It's really up to you as far as when. Adn....JDM is a good choice for the mods.
