i have had the same problem and still do, i think its my tune. i have a h22a swap and what happens is as i accelerate i will hit vtec and at around 5000-5500 it leans out, or the opposite, and what happens is i feel a noticible decrease in acceleration and the rpms bounce a little, is this the problem you are talking about?

i think i found the answerrr ... bro ..if u might need help too .. idk ....check it out tho


(((((some chips have 2 step programmed into it. and its set until 5mph. if your speed sensor doesnt work then it will stay in 2 step because of your speed sensor. put a stock computer on. if it still does it them it is your tps sensor i believe. might be your map sensor but just put a stock ecu in your car. if it runs fine then its the chip. if it still runs the same its either your map sensor or tps sensor)))))
