This is Novitec's piggyback module specifically for McLaren GT (will not work on other McLaren models). Adds 60hp plus significant torque, although I suspect is higher than that as you can definitely feel the difference. Do it yourself install that does not affect warranty as its a piggyback, plug and play module with complete, easy plug specific color markings and inert plugs for existing vehicle plugs.

Purchased module new in Jan 2022 for $5420 (have proof of purchase) and used it thru April 2022 where it came off for a full Stage 3 upgrade by Weistec Engineering.

Shipping included and I'll offer a 30 day money back guarantee if not satisfied.
