Yes I figured. It had a few boost leaks and other minor things that needed to take care. I guess that threw the tune out of alignment and bogged it down real bad.

Hello Tuners!I have a dilemma here, my transmission was making it really bad noises and I took it to the shop that I have been working with for other minor stuff. Now after cracking it open they found that the teeth of several gears were broken. After waiting for so long they giving me the...

Ill check that when I get home in a few days, now if that were the issue how could I have some sort of Idle even if its holding the pedal for a little bit before the IAC motor kicks in but before reaching operating temperature? Because as of right now, I have to have the gas down until the fans...

Hey Guys!I have a little issue here. So my car was running okay. I was told it had a bad Idle valve which eventually I replace for a new one (did not feel any change in idle after replacement, but did not tune for it either). When the old one was on it was tune so shortly after revving it for...

Hey Guys,Had this question lingering. When I got my car, it was running what I believed was fine, then over time it started getting progressively worse doing shakes, stalling, weird idle, to finally not wanting to stay on. I had someone take a look at the car and do some idle, fuel and timing...

I want to give you guys an update about my shaking. In my case my car needed some adjustment/tuning. I had WayneSpeed come by and check it out. After several fuel, air and cam adjustment the shake was totally gone. So after you look into all those bushings if you problem persist consider...

Let me know your findings, perhaps I can guide myself as well while I diagnose mine as well!

Thanks for the tips Spiro. Ill be reading the links you sent. I already bought the gage and will be replacing it shortly. I replaced myself the CAS, so I guess I did not do it properly. This is a picture of the ecu that is in the car. When I looked it up it said 2004 Evo VIIIIll definitely...

Here is a close up of the CAS@Spiro2k6 I do not know if I am using a 1G CAS on a 2G. Shine some light, I replace the sensor with the one the shop had told me I needed to get. I had gotten another round one all metal and the guy turn me away telling me it was not the one I need it. After that...

Hey man!I am having the same issue. For me it usually happens when I am driving at any gear and above 3.5k RPM at wide open throttle. If I have the throttle 60% or closer its okay, the moment its about 75% to full open it starts shaking as if you were going over a cobblestone road. Very...

Hello Guys!,I just bought recently a 97 GSX, I am new around here and to the 4G63 realm all together. It has been a very steep learning curve with a new engine and turbo but I am holding on to it and coming up slowly but surely!So I got a few issues I need to iron out but do not know where...
