heres what i have a stock d15b7 i just replaced the head gasket cuz it was leaking into cylinder 2 toured everything to spec connected everything no problem i put rc 440 injectors it would run right so i put the stock ones back in ran fine no problem then i noticed that when i drive it wont let me rev past 4k after like first gear like its at a fuel cut der no cell up except for 02 sensor cuz i cant connect it but will so does anyone have an ideal what could b doing this????

 

Is the car tuned? Im having a hard time understanding what your doing? Is the car running on the stock injectors or the 440's?

 

no its on the stock ecu and stock injectors

 

And its turbo'd?

 

yhea i have a t25 with a blox map sensor bypass valve so i dont keep getting the cell for map sensor

 

You shouldnt be driving around untuned in the first place imo. I can almost garranty that all the problems your having is directly related to tuning.

 

yhea i know im waiting for payday to go get it tuned but thats what it sounds lik a tune to u iv never turbored so im confuesd

 

What you should do is throw away that check valve pos and take the car to the dyno.

 

yhea im only got it so i can drive to wrk with out the cel coming on and going limp and acting dumb but i do wanna go get it tuned
