Has my standard ecu been remapped

[scooberblue]

Hi everyone.

I bought a my99 v5 classic an it was standard
Bar a full scorpion decat system and a prodrive
Style Y pipe under the intercooler.
It boosts well an holds 14psi steady an tails to
12psi near the top of the rev range.
I have a y7 ecu from my old scoob an when I put
It in to test it the scoob doesn't pull as nice or as quick threw
The gears an the boost gauge is constantly pulsing between
16 an 12 psi all the way up the rev range?

Has the original e3 been mapped for the decat
An is there a way I can find out?

It happens that the original ecu of the model MY5 V5 is the AE800 which is very good mapping, more aggressive than the AE801 and AE802. The problem of the ecu AE800 is that it stays very thin in high range and can melt pistons, it is your only fault.
