ok this is the deal, i have a very slow 02 neon (auto) i was told if i get the R/T head and PCM i will gain and notiece HP diff. Is that true? i hear everything is str8 bolt on. my questions r

is that true?

could i get the PCM and just put it on my car without the head and notiece a diff?

do i have to reprogram the PCM to match my car?

does it have to match my VIN?

 

First off, an R/T PCM will not work with a automatic transmission. I have no idea what your talking about when you say "srt8 bolt on", care to explain? You would have to get your VIN flashed into the PCM which most dealerships will not do unless your original PCM is damaged. You can buy a brand new R/T PCM and have it flashed but those cost upwards of $1,500.

You have an 02, if you want a new PCM just buy this...

2 months ago my car would go pass 20MPH so i took it to the mechanic. he told me luckly it was my "TCM" tranni comp that messed up so i he got one and had to get it program by the dealer for like 330$ the car runs very very slow. it hesitates and has no bottom end wut so ever. my girl has the same car, year color u name it and she takes me by 2 cars. i only have a CAI and a muffler, shes stock. th mechanic also check to see if the exhaust was clogged but it was fine. my sprak plugs r new, i have new injectors. but nothin same thing. resently i was told the computer that the mechanic put was for a diff model or for a manual. friends of mine that r also into neons say my torque converter is lockin/not lockin up, one of those 2. dat is has to be with my computer. im tired of spendin money to get no were. m y tranni fluid smells normal not burnt. so im lost in wut to do next, any suggestion, anyone i can give my vin and part # from the computer and see if it matches, like ppl here, ill have to pay 120$ at the dealer, plz help

 

considering its a second gen car, I would think you would still have the warrantee on it. Muffler and intake won't void it. So check it with them and give them everything thats wrong. It does sound like either your ECU is improperly flashed... might be glitching somewhere, or there is something bad going on. Does it give you any error codes?
