hey guys

got my evo out of storage today. Full bolt on 9 RS its been sitting for 5 months with a full tank of 93


drove the car today and it feels really slow. my boost levels are at 20-21 should be 23-24

i have an electronic boost controller.

drove my friends exhaust only evo and it feels faster when my car was running right it was much faster then his.

Could this be due to bad gas or something else?

no changes have been made to the car at all since i parked it.

let me know

 

I would lean toward bad fuel since its been sitting so long, did you use any fuel stabilizer? I would drain the tank and get some fresh 93 in there and see if that makes it run better.

 

drain the fuel. what are your afr's looking like?

 

afrs are high 11s should be 11.3 but I'm not sure how bad gas would make the car boost 4 psi lower

 

i also did a boost leak test nothing wrong there
