Ok,, here is the next move. i didnt know while changing 3 afms, mech rechanged my settings and i was still trying why car is jumping so quikly whenever i touch accelerator paddle,, yes racing guys love this feel:),, too rich tuned engine.
so i called up spectra to take look at engine, i went to Isd and busted a tire as going to dirty/bumpy areas and car left with mech,, somebody reduced tire pressure or what
so he reduces tps which was sitting at full, i dont know how it went to full - car is tuned better now,, next comes the muffler part as people outside car complained more than person inside car about loud exhaust so i went and bought Mitshubishi S10 muffler, , took off its pipes and got it weld first near the o2 sensor, but exhaust noise didnt decrease much so i took muffler off from under driver seat and left a resonator there and weld the 3rd muffler near exhaust tip, and found the torque increase less exhaust noise and some top power rpm reduced.. that's ok for me during daily driving i dont keep reving it full, so drive is grt with less exhaust noise
