I got a Dinan flash on my stock n55 last week, I plan on doing more next year, but don't know if I should stick with them. Are there better alternatives?

What are your goals? What is the car being used for (primarily daily/weekend driver or track/autocross) What flash did you get?

Looking to get to about 500-600whp. It’s my DD until I get my e46 325i to pass emissions, I also have a e36 M3.

You'll want to get the following then:

and possibly JB4 for the meth controller

With those power levels, maybe consider going with larger diameter wheels, better tires, better brakes (maybe an upgrade from the m2c), probably coilovers.

If you're planning on doing anything other than a straight line pull here and there (i.e. tracking), you'll probably need to look into other cooling upgrades as well

For that kind of power, you need a stage 2 turbo. Pure or Vargas preferably.

You will need a flash tune that allows custom maps. Dinan might not be the best option

Ok, thank you all
