Ok little update..
Had the guy back who mapped it ..
Told him I wanted a standard map put back on it.
And to my surprise it's now running 211bhp,
Bit shocked as it was running 245ish before..
So it would appear that it already had been mapped..
He then put a map that he knew was ok,told he got it from his supplier/bloke he knew.
Now the cars not spiking at all,just holding a steady 16.5psi.
Bhp is now 253bhp..
Does this seem correct for a car that has decat,stainless pipe,k+n,forge tip,bov???
I did think the power was good at 245 with just the mods listed..
Sum it up,revo looked at the car in the first place,ready for stage 2 (told it had a stage 1 map by them)
The car did but was demo software,that had run out..
And had been remapped by someone else..
