ok just got my b16a3 motor tuned. mods are just aem intake, dc header, itr cams, and 2.25" piping muffler to an itr muffler. before the tune when running my stock p30 ecu it ran perfect and got me about 31-33mpg. now that i got the car tuned on chrome with a chip p28 ecu the car runs stronger but sometimes at idle it would idle higher then normal around 1.1k-1.3k rpm and it would kind of jump around sometimes. it dont do this all the time only sometimes. also now that i have the car tuned i been getting like 26-27mpg only i wouldnt think that a tune would make that much of a difference in gas though. my driving habbits are all still the same i dont really drive my car hard at all i always shift around 3k rpm. anyone with chrome tune having this issue????

 

Did you have the car tuned in person ?
If so, take it back to the tuner to have it touched up.

 

yeah tune in person

 

he probably tuned you for super reliability and maybe your tuned at 12.6-12.7 afr. maybe your car was running lean before now that it has the right afr gas aint so good.. take your car back ask for your money back or tell him to tune you on CROME not chrome

 

haha just a misspell i guess haha thanks tho

 

im just being a dick
