After 3k rpms, the car feels great and accelerates with no issue whatsoever. This mostly happens while on 3rd gear. i havent really changed my style of driving, meaning that this is something i was not experiencing before. Ive seen a few threads on this issue but no one seems to find a definite solution. Ive filled up in different gas stations with shell 91 oct (this is the best we have in PR unfortunately), cleaned maf sensors with maf cleaner, reset ecu disconnecting the battery but the problem is still there. Only mod is z1 maf hoses and K&N drop ins which were installed 1k~ miles ago and car felt great after install. If anyone can chime in on this, i would appreciate it. Either way, i will take it to the stealership if i cant solve the issue, but was interested in solving it myself if it was possible. Thanks guys! 
O.ooops. Just noticed i sorted of posted in an incorrect area. Sorry mods, if its necessary please move to correct area. Thanks |
first things first, ditch post maf tubes and get a real intake, id suggest takeda stage 2 cold air or stillen Gen 3s
second get a lightweight flywheel, clutch, CSC, and new CMC(you need to change the CSC and CMC to support the new clutch and you switch the new clutch because you are changing flywheels) these will help out the hesitation the most
third, test pipes and an exhaust
all of those should help out hesitation, i dont have that hesitation anymore and i dont have an exhaust(stock nismo exhaust) the hesitation you have is completely normal though, only real way to fix it is with a tune(it has something to do with throttle maps or something like that), all the mods i listed though will help alleviate it though
