computer problem... fuel map air- fuel ratio needs to be reprogrammed.. remember- if this is done- it voids mitsu warranty. 2 choices- either put stock back on, or lose warranty and have a mechanic reprogram....

 

been workin w/ air intakes for a while...i, even modifies tubing. been doin that since my 97'mirage,00' eclipse r.s. and 87' starion. and now planning to do the same w/ my outlander, which is equipped w/ 4 1/2 filter and 4' adapter. but so far none of them fail.you may want to shave the adapter opening, sometimes those adapters have small opening (air). i, did that to my brother's 03' lancer, after shaving the lips,(adapter) car went smooth. another thing, check the sensor inside the hive for damage.
