i want to know. i heard there is a way that you can make your horse power go up from 217hp to 260 by upgrading the computer. Is it true. Should i get an resurculating blow off valve for my car. Anyone that has an evo can they tell me what there horse power is cause i dont think mine is right it sya mine is 217hp on the dyno. by the way my name is Nick

 

Read the dyno thread. Personally I went from 232 HP to 269 with piggyback computer (Apexi SAFC II) an air filter, and a manual boost controler.

Wow, that was painful to read. Nick, any reason this was posted in the installation/howto forum?
