I was having fun on my car for the first time after installing 650 injectors, Logic Intercooler Upper and Lower pipings, and fuel pump. Current mods are HKS DP, UR Hi flow cat, HKS CB, HKS intake.

Here's what happened. I floored my car on first gear. WOnderfully smooth power band until redline. Switch to second gear, floored it and at around 5K rpm, there was a slight bog and then after the bog, it went back to normal. It felt like a sudden choke as I suddenly let off the gas for a millisecond.

Here is what I can deduce:
1) Intercooler piping is still not tight enough (Can't be because I tightened the **** out of them)
2) Car is running too rich without a tune. I am waiting for my cam install before my tune
3) Spark plugs are shot (Got new sprak plugs will be changing)

I am thinking the plugs and running too rich. What do u guys think?>

 

uh.... yah! you are running too rich. how much boost are you running?? don't tell me stock. put your stock injectors back for now untill you get the cams installed and tuned.

 

You need a tune for the intake and the injectors. The intake without the tune will make the car run lean, becareful running the car like that when it's hot out it. Take the intake out and run the stocker till you you get your tune.

 

Could it be that he is hitting a boost cut??

 

no way. I already have a tune for the intake back in 2003. I am already tuned for exhaust, DP, cat, intake. Now for the rest of the stuff.

Anyway, installing cams tomorrow...cant wait to hear to sound of it.

I think I am running too rich right?

Boost cut?? I have no clue but I have an HKS EVC V highest recorded boost was only 19.6 psi because I lowered it since I dont have the correct tune yet.

Thanks for the help guys.
