Stuck at 6.5k sounds like limp mode/safe mode.go diagnose your ecu for error code.
Maybe some sensor aldready kaput! You need to find why your ecu burn also.else it can effect your new ecu too.

Go diagnose error code 1st and i think u should correct ecu or can kacuk v6 mivec ecu

change your coolant sensor. should be ok after that. mivec ecu require the temp of your coolant more than 60> degree in order to open mivec. another thing dont direct spool ur radiator fan as it might bring down the water temp too low.

Yes, you got that right, it is a replica, not the original Italian hotshot roadster, this Lambo is made by an experienced private builder. With 3 years of experience, I don’t think he did a bad job at all, well maybe for the interior a bit. Here’s the details:

Drivetrain:
Chevy 5.7L Vortec Sequential Fuel Injection
CSI Electric Water Pump
K&N Air Filter
Performance Tuned Computer
5 speed...
