- VZ SV6 M6
To anybody that knows a bit about tuning the alloytecs, i have a question.
i have a VZ 190kw sv6 manual, have had it dyno tuned, along with a host of other mods, have run a 14.9 before, so i know it's healthy.
I took it in to a tuner to have the RPM limit upped from 6700 to 7000. which i don't think is a huge ask, ive seen videos and instances of alloytecs revving that hitgh without too much of a problem.
the tuner called me not long after i dropped it off and said that it was already set at 7000, the engine just wouldnt get there... and then tried to tell me it was stretched timing chain and because its a tired old motor etc...
Now, i admit the motor has done 260,000 Kays (alot)... but the coils, plugs, injectors, intake manifold (cpr6), exhaust, 20%underdrive, and a host of other things are less than 20,000 kays old, i did an overhaul not long ago. and as i said, the motor is still as healthy as anything, it's run a 14.9 not long ago and still goes MUCH quicker than standard. It doesn't blow any smoke or anything either.
And i know when i hit the 6700 limit, its still pulling hard, it just hits a brick wall. it doesn't gradually slow down or feel like a drop in power, it just dies as soon as it hits 6700, the same as it did when i bought it standard 150,000 kays ago...
So, anybody that is knowledgable in tuning and these motors, is the tuner pulling my leg, or could it actually just be suddenly stopping at 6700 because of parts? There are no sounds from the engine or codes for timing chain wear, is there possibly a parameter in the computer that the tuner hasn't set properly?
