ok lately i got my car tuned with the cams and i turned the boost up to 21ish.....it seemed good at first, now it doesnt seem like it's pulling as hard, like when i hit boost the rpms dont climb to much faster, like they used to. At first i thought the clutch was going out but, the rpms would shoot up then....now i have no idea what it could be. I think it could be pulling timing or possible a boost leak. My boost will hit like 21.5 then sometimes it immediatly drops to 20 and sometimes it holds alittle and bounces back and forth between them then sometimes it just tapers to 20.

 

Where do you live. Its been nothing short of 85 here every day and the car sometimes feels like a plow.

 

Find someone with a logger and log a 3rd gear run. If timing curve looks ok and you find no boost leak then I'm gonna have to say it's the heat.

 

Its hot out here also, and it is a plow!!

 

its somewhat hot but still it really makes that much of a difference?

 

Yes THICK AIR!!

 

I am experiencing something very similar.
Dont be too worried man.
It's the heat (not enough density) that is robbing our cars HP.
It's been around 90-95 degrees here for the last 2 weeks and the car definitley hates all this heat.

I would start worrying about it when it's cool outside(around 60-75 degrees).
I am 90% sure it's the heat causing our cars to lose HP.

 

ya like the car still accelerates pretty good it just you cant feel it like you could before its like the torque droped

 

yea once it starts cooling off eventually u will see that there is nothing wrong with ur car

 

im glad someone asked this cause i was noticing this as well on my car. i can tell a big difference though when driving at night right after it rains. i will really find out when i do a dyno run in the winter and compare the two.....

 

same thing here, car pulls slow but as everyone has said, it is the heat.

 

I'm sure it's a toss up between the heat and getting used to the power.

Time for more parts.

 

am i the only person that noticed that he got his car tuned AND THEN turned up the boost? does anyone else think that's a bad idea?

 

It was a mail in flash and i told them the boost i wanted to run with it so once i flashed it i turned it up.....

 

quick test.. drive it early in the am or late at night... and see how it feels compared to the day.... i noticed the same thing, and after going to get gas and feeling like i did when i bought the car, its the damn heat
