Hey guys its me again I found a couple new things im thinking about doing to my car can i get some advice i will leave the links beside the description
Digital Hp PCM-249$ http://www.pfyc.com/pc/MC3002/MCUNDE...nte+Carlo.html
Throttle Position Sensor Enhancer-85$ http://www.pfyc.com/pc/WB3013/MCUNDE...+Enhancer.html

 

the PCM is a good idea if you have a few mods, the TPS enhancer is junk. and if you get the pcm you wont need the enhancer at all.

mods to do first are burried in this site and others, but the ones i recomend are:
-cold air intake like a FWI
-exhaust (ubend delete, new down pipe, replace exhaust with 2.5" piping ect)
-TB and intake manifold mods
-ported exhaust
-smaller pulleys if you have a SC

but i think the best investment if you plan on doing more mods is a tuner. it will save you a lot of hasel and keep your car running better.

 

X2 Those TPS sensors are useless. All they do is send an electrical signal to say you have the throttle wide open when the pedal is depressed to around 70% or so.

The DHP tuner is good but their customer service sucks bigtime. I'm going with HP Tuners. It costs a bit more, but much better cust service.
