No mods at all all stock got into a accident they put everything together nicely got that like after I drove off the shop took it back no leaks and it hesitates just a tad 3500 to 4200 Rpm I'm putting premium 93 in it all happend after I got it fixed I reset the battery after maybe 20 miles the engine and code comes back on and I get the air to fuel ratio unbalance Sucks bro
