Alright I have a series one supercharged, When I hammer down on the gas it used to leave a bit of rubber and now there is nothing, The car seems to sputter up to speed when I have the gas all the way to the floor, Anyone recommend anything Im kinda of in a pickle at the moment,

Gas down and it goes just seems like everything is spinng but no action, I dont get it, I had the LIM redone about two weeks ago, and the motor area seems to be very hot, but no overheating by any means,(thinking out loud)

Where do I start?

A common start would be to check the fuel pressure at idle, with and without the vac line attached to the fuel pressure regulator. Preferrably after driving for a while.

How old's the fuel filter? If it's plugged, it's starving the motor for gas. $7 for a new one. ;)

Clogged catalytic converter? That'll cause heat, definitely around the cat area, not so sure about engine bay area.

Nice job finding/fixing the problem.

platinum plugs of any brand aren't a very good choice for your car.

He's right

I run cheap copper Autolites in my car, along with dozens of others that don't want to pay for the NGK's

Did those iridiums have the screw on ends where the wire connects? I've found them loose in the past and causing an issue.
