you may want to restructure what you have written as it is very hard to make sense of.

Are you saying that when your car spools up it lights up the tyres and you have onlt mildly modified the exhaust? Had is since new? would a previous owner have flashed it? Got cheap a** tyres made out of melted down vietnamesse used condoms?

Or are you just trying to make a blanket statement that your car is awesome?

More info please. Also tell us what brand and size your rear tyres are.. also tread depth.

Bit hard to understand but I would say your actuator is probably stuffed and your overboosting.

my brohr insturbo xr6 had a similar problem turned out the people he brought it from hardly ever hit boost so everything was gummed up with crap, as soon as it started to loosen all the gunk up he broke the bypass valve and the hose for the map sensor, which was only split but was enough underboost to leak so it wasnt reading the correct amount of boost, went good untill the engine had enough and threw a rod into the side of the bore.

there is only one map sensor and has no effect on the boost of the turbo...
maybe you mean the factory boost controler, wastegate actuator???

Autometre is just about to release their new range of boost guages. After 30psi they will be marked HEKTIK from 60PSI they will be marked EPIC!

ill suggest you go buy a boost gauge and get someone who knows what they are doing to install it. easiest way to see whats happening with your car, it should be putting out 4 psi and stay at 4 psi untill you release the right foot. You may have s**t tyres on your car, if you have any leaks you wont over boost, you will loose boost. there is a valve that sits just under the battery tray (right hand side) that reads pressures, forgot the name of it. Remove both hoses from each side of it and spray inside the valve with contact cleaner.

Also it sounds like your car is hitting boost way to late, maybe your actuator is sticky and staying open, then slamming the waste gate shut making 4psi causing your (wheels to spin) at 3500rpm.
