Stage 1 is slower than stock unless you tune the car's fuel. A guy around me flaunts his SRT-4 like "Yeah it's staged." My brother ripped him apart & asked why the guy lost to him @ Maple Grove Raceway... Turns out the guy doesn't have the right stuff to tune his car, so all it does is dump more fuel than what's needed. The kid didn't even have a boost controller to even try making it stoich. Word of advise for you SRT guys, first thing: BOOST CONTROLLER!... Oh after that race my brother turned on his 100 shot nitrous & left him @ the 1/8 mile. LOL!

stage 1 for an 03 srt-4 is a new ECU and injectors and for 04-05 is jst ECU which is a gain of 10hp not much but pple usually get it so the check engine light wont come on if they dont have a cat on the exhaust stage 2 is about a 30hp gain ECU, bigger injectors and turbo toys...intercooler sprayer and high octane mode(HOM) and state 3 is a little bit bigger turbo, ECU, wastegate, and other stuff withought turbo toys its 310hp and with toys(HOM) its about 355hp

with the right basic mods you can put down some serious numbers. and srt4 cannot have there ecu tuned like evo and chevy. they have to be upgraded

A bigger down pipe and ecu tuning.

what dose stage one mods include?

stock turbo likes to wine at you when you stomp on it, lol. freaked me out when i first heard it on my car. hey what mods you got? you got some good numbers there.
