Hey guys , It was my forth day with the weistec's stage 2 . I really liked it . Then suddenly when i was cruising on comfort my engine revved up . Then i got scared and stopped on the right . And got this message "Rear axle lock differential innoperative". I turned off my car then turned it on again same problem . Whenever i accelerate nothing happens just engine revves up and i hear a whistling sound from the diff. But the car still moves when i release the brake . But doesnt accelerate (i dont know whats the word) , all throttle response revs up the engine and the car is not accelerating and sometimes the car suddenly switches to neutral and i get the message again , also engine light on .

Is this just a safety issue ? Or does this mean i have a slight issue or that i need to change the whole difference ? Should i remove the weistec downpipes tune and filter and restore stock ecu and take it to the agency and fix it on warranty ? Because warranty will go away if they found out i tuned. Please help guys . And thanks❤️

Call Weistec ASAP. It could be a software glitch. They will reflash your ECU and you can try again.

FWIW: This is a first occurance of this issue stock or otherwise.

Please let us know how this comes out.

Best wishes

Really Mnalmana? Fourth day? Aren't you the guy who said on November 19 that your car was slower after you had Stage 2 installed.....

Ya, this guy is a troll....I'm guessing its a fake post.

Things slow in the call center today?

Not a troll , not a fake post , im not on here much just when i get irritated by some problems. I got it retuned by weistec and then that happened at the 4th day , also i have a boost leak. Fixing them now . Might explain the 507 rwhp ...

Fyi my instagram @mnalmana
