sup people, i just installed a tdo518g turbo on my interga gsr. i noticed when it hits vtec it seems to hesitate for a split sec. now i know what your gonna say its normal, its just hittin vtec, well i had it for 5 months befor the turbo and it never felt like that. also there semes to be a smell like exaust in the drivers compartment when i turn on the heater. Any ideas!!!!!!

 

i would say the hesitation has to do with the way your car is tuned. its either a fuel problem or your timing isn't right. how is your car tuned? just the greddy e-manage or the "blue box" that is untunable? and does it studder at 4400 or 5800?

i have the greddy turbo on mine and my car boggs at 5800 because there is a flat spot. in two days, its getting tuned with uberdata and that will be gone. yours might be the same thing.

i wouldn't worry about the smell, i get it too.

 

i dunno but maybe its an exhaust leak?!?!! check around your manifold. Sometimes under light pressure it doesnt leak much and won't hurt performance. But under heavy pressure like when vtec kiks in.......well it stutters. does it come in and out or just at that one point

 

hey im having the same problems with my gsrturbo. it kind of stutters at around 4500-5000 . and i as well have a very deep smell.... gets me kinnna light headed haha.... but im sure wen i get it tuned it should be running better... im still running the piggy back ( blue box ) not sure what to go with.. i was thinking hondata.. but thats alot.. does anyone know how much they run for... or any other good ecu's ... and give me the prices if possible

 

hondata is good, but if you say its too expensive for you and you feel like you might wanna tune it yourself, look into uberdata. its free.

 

yeah sometimes the smell gets a little overwhelming. but the hesitation is round 4000-4400. i think u r right about the tuning. i plan to go to get it dynoed when i get the money, i would like to c the strong and weak points. but thanks 4 the help. any other suggestions are more than welcolme!!

 

Your car is running rich. What kind of fuel management are you using to suppliment the boost?
