I got ym car mapped by a "decent" local tuner and about 5k after that my first and second synchro went and grinder like *****, got a brand new gearbox put in and 3k later exact same issue with first and second. Will this be down to him removing some torque limiter? (guess work) or will there be another reason I'm going through boxes. Just seems like it's too much of a coincidence that after putting 38k on the car it's gone through 2 boxes since a map. Tia

Just what may appear a ‘daft’ question but mapped to ?

It's probably the map. The gearboxes aren't rated for much more than stock output. You can expect to come across issues at the 140 mark I think, take it back to stock if you can.

Grearboxes are rated to be fine as long as it isn't over 200ft/lb of torque and can take 175bhp ...... Bud depends on driver and map also
