(car: 1988 rx7 t2 with s5 jdm motor swap) car under low throttle pressure kinda feels like it chuggs other than that it runs fine.. mods: 3in down pipe and i think its chipped not for sure though.

 

We need more information if we're gonna answer that. These cars tend to "chug" at especially low RPMs, especially when you dont' give them much throttle. Is this a recent problem, or an ongoing one?

 

i mean like 1/16th throttle mayb like 1/8th throttle.... not exactly sure.... but it like the motor chuggs is like all i can say like if i am tryin to stay under boost and just drive and give light throttle it i guess id call it chugg.

 

How low of RPM are we talking here? This is what happens with worn engine mounts and no low end torque.

 

its like when im going at say 55mph and i give it more gas like get into boost then like let off and give very little gas and it does it like i said 1/16th to 1/8th throttle
