I have currently a M2 Aluminum intake, Efini Y-pipe,and a 3" SS downpipe. Stock exhaust and cat... By boost is 12-10-12. I got a response from before that this is pushing the stock ECU's capabilities...

My question is: Can I install an ECU mapped for Intake, DP, Exhaust, IC and Midpipe first? I know it will run rich, but how rich is TOO rich? I will do the mods, but I cant afford them all at once...Next will be the Catback, which would have hit the 3 mod mark... But I'm a bit worried! Thanks.

 

I'd suggest your next upgrade be an ECU.

Spark plugs are cheaper than a rebuild, so it's better to run rich then lean.

 

Sounds like a reasonable answer to me... Just wanted to know so I can put a WTB: in the for sale section... THANKS!!

 

How long is it until you plan to install an i/c and a midpipe? If it's going to be a while, get an M2 Stage II chip (or equivalent) that's tuned for intake, d/p, and exhaust. If you get one used, you'll be able to sell it for pretty close to what you paid for it when you upgrade to a midpipe and i/c.

 

Well, I should be able to get the IC soon. I don't know if I will even run a MP... But I hear that a Efini Y-pipe does increase flow somewhat so I figured why not... Do I buy the chip already in an ECU? Or is that another story? Thanks for the help.
