AMG GTS W2 Slower than stock
The title says it all . I own an AMG GTS edition one . I was very happy with my car I love it so much. But i was greedy for more power . I went with the weistec stage 2 . Installation was perfect . Although the tune ... Not so much . No problems with boost . The car just got slower. I raced a gt3 rs and it won ... Im sending my ECU tomorrow back to weistec i hope they solve my issue. Any thoughts on this issue guys ?

Did you do a baseline dyno first? Hard to say but sounds like the ECU is likely the problem.

My buddies stock GT3rs is running 11:teens-20's all day long and my GT3 is running 11:25-30's, they are fast and hook real well. Typically tuned GT's have traction issues when racing, any when you raced the RS? More power doesn't always help with these cars drag racing, but more from a roll 60mph on. From a roll you should pull on that RS real easy.

i used to have traction issues while stock but now my car rarerly wheelspins on second gear , same tires same everything . Im like a stock corvette c7 level . Not even close to a ZO6 . Im really irretated by weistec . I didnt expect this at all . I payed a total of 11k dollars to get my car degraded ! Total disappointment

Why don't you talk to them first before going straight to the forums, could be a simple issue.

Good advice. Also, with no pre-tune baseline, "slower" is meaningless. Ditto for a street-race outcome.

Thank you
He'd prefer to whine on an Internet forum than work with the aftermarket vendor who's product he's bought. I say that as a deep skeptic about the aftermarket generally......the result of much experience. BUT, first you give the vendor an opportunity to address your complaint.

Most likely another lurker who does not really own a GTS. Gee, while I'm on the forum, my Ferrari 250 Testa Rossa has developed a wheel wobble at 220 mph. Does anyone know what it is. It was fine before I hit the curb.
