Changed Spark Plugs then Installed Cobb

After doing that the car pulls like a freight train. The question is, what's next? MY fuel pump has not failed and neither have the turbos. I want to add more modifications to my car but don't want to have to remove them when the above mentioned components fail. Alternatively, I don't want the downpipes or IC to be the reason why the dealer doesn't cover my turbos or fuel pump.

My thought is now to go to Cobb in Plano and get refined ProTune + 30% E85. This way, I can pick up another 30-40 HP and have an optimally operating car. when the fuel pump fails, I'll just remove the cobb and take it to the dealer.

Do you guys thick this is a good plan?

why or why not?

I also changed plugs and installed Cobb today, oddly enough also in NOVA. I put an intake in as well and am probably going to start shopping around for a font mount and downpipes. I would just go full bolt on and maybe keep your stock parts if you're that worried about it. That's probably my plan but my car has low miles so I'm not really worried about the turbos.

You're plan is good, but you really need c@tless d0wnpipes and an intercooler, but this could lead to an issue with the dealer. The intercooler is not really an issue, but if you dealer is cool with mods, go for it. DPs were my favorite mod next to the tune.

COBB in Plano? Texas? Why would you do that when Jake from PTF is 30 minutes away from you?

You can only go so far on stock FMIC. The stock FMIC is inefficient even at stock boost levels.

The FMIC for a proficient backyard mechanic only takes about an hour or so. Just remove it before a dealer visit if you are that worried.

I'd sooner recommend an FMIC first as the Cobb Stage 1 + FMIC maps are very powerful, more powerful then the Stage 2 maps for downpipes.

If you are still wondering why Stage 1 + FMIC is more powerful then stage 2, it's by no accident, as the stock FMIC is very inefficient and the stage 2 does not require FMIC.
