Throttle Response

so i have a 09 xfe coupe, and the throttle response on my car, well it isnt there. i push the accelerator and it takes about half of a second before the car actually begins to accelerate, almost like theres a delay. its been like this since the day i got it. has anyone else noticed this in there car? what could be the cause of it/can it be fixed?

manual or automatic?

automatic cars have a little more delay in throttle compared to manuals.

All the XFE's are manual.

Most of it is the fact that we have electronic throttle's.

The only solution I've heard of is a tune. But a tune is worthless without a fully bolted car. You have a long way to go, there is no quick solution to that lag. An intake will help a little though

It's called 'Fuel Enrichment Delay' and it's part of factory tuning in your car. Basically it takes your car's PCM a bit to decide whether or not you really mean to go WOT. A Trifecta tune will eliminate this but as other's have said it's not smart to get a tune unless your fully bolted. Otherwise you won't see the full potential of the tune. My suggestion since you already have an intake is to work on your exhaust...header/downpipe/cat-back will help your throttle response. I've also heard buying a Corvette really helps ;)
