That thing was like a bullet at :40 sec

[@erictyler5938]

Which is the better aftermarket parts for these cars, Renntech or Weistec? I'm looking at picking up a AMG/GTR myself

[@grahamrahalperformance]

We have been very pleased with Weistech! We are dealers and also have a Cypher Pro to tune in-house.

[@camirocz]

So? All that and no numbers? Whats the point?

[@grahamrahalperformance]

Our client did not want the numbers disclosed to the public. But we wanted to at least share the sound and what had been done to it!

[@camirocz]

@@grahamrahalperformance o would never post a video like that no numbers I don’t see why he cares about who knows the numbers he isnt racing anyone for a huge purse .

@@grahamrahalperformance thanks Graham ! do you recommend the KW V4 coiler upgrade for the car?. I track the car very often and find the front end grip is pretty ordinary.

[@grahamrahalperformance]

@@ridwanhasan171 KW's are a great option! We are dealers! If you are interested in purchasing, please email [e-mail]

[@kvgable]

you didnt have to post his numbers you could just post the diffrence these parts make. like +150hp and +150lbft up top with more under the curve. id guess like 650hp and 700+lbft

[@grahamrahalperformance]

Hello! We appreciate your feedback, moving forward we will add more specifications. In the case of these particular upgrades, the Weistec downpipes, according to Weistec can add around +192hp/+287tq. The Weistec tune is noted to add +149hp/+181tq! Stock numbers for these is 456hp/443tq.

[@kvgable]

@@grahamrahalperformance now u know the downpipe numbers already assume the tune. Dont be disingenuous people are looking to these posts for information

[@tyronecarter1317]

@@kvgable Disingenuous? They just gave you the numbers. Maybe you can just google next time instead of being rude. They literally listed the mods on the car at the start of the video and all the power information is on Weistec's site.

Low power

What a wicked looking car!!!

what is the purpose of posting dyno videos without the dyno chart before and after?
