- 12 Regal gs
Hey everybody, i recently purchased a 12 regal gs 6 spd. Did some reading on this forum (kinda makes me wish i didnt get one but too late now) and the car already has some mods on i. Just kinda wondering if the mods are good or not. Mods i know it has is a zzp intake. 4h short throw shifter, intercooler piping/ intercooler and boots look aftermarket, brembo front calipers, exhaust has mufflers welded on that dont look stock (no names or anything). Car has a boost guage and pegs around 25psi which makes me assume it has a tune? Im used to diesels and 25 psi seems way to high on this car is thats even accurate?? Kinda looking for help on if current mods are worth keeping and how to tell if car has other mods (turbo, downpipe, pcm, tune etc) thanks in advance. Sorry if this is a super common question!
