Dear AMG owners,

I'm thinking of upgrading my gl63. Am deciding between alpha 700 (ecu remap) and weistec (ecu remap, air intake change, spark plug change) Appreciate your advise and comments. FIY, alpha is the tuner that did the R35 gtr.

Thanks and Best regards,
Albert

Weistec and renntech seem to be the big players... I've ridden in a weistec GL and it was pretty impressive.

I'm now leaning towards spending money on a laser diffuser and an axle back exhaust... That away I can actually get more mentaland wood stimulus than waiting for some Cayenne turbo to pounce on...

I already did the intake...

I did Brabus ECU on my previous G and it was awesome. I know they want 9k for the upgrade but it's worth it

I have weistec tune on my GL63 ...18k miles and still running strong no check engine light. The GL literally chirps into second gear

I would also love to throw our hat into the ring as well!

We have tuned thousands of cars and offer one of the best engine coverage warranties in the market!
