so every time i accelerate my evo makes a rattling noise but it only makes the noise when its under 2000rpm every gear except 1st does anyone know what it might be?
too much load under low rpm, kiss your rods goodbye.If it's stock exhaust then yes, it's your driving. If it's a loud, rumbly exhaust then it's your exhaust.
If it's a vibration that you feel vibrating your entire buttocks, then you are simply giving way too much throttle at way too low of an RPM...
Keeping it >3k rpm all the time is a stretch to say the least. You can drive under 2k rpm no problem, I do it all the time... the throttle position is key though. I tend to gently caress the throttle when I'm that low, then at 2.5k rpm it'll take whatever I want to give it. I've logged what my tune is set up for and for my particular tune this is extremely safe. I only hit like 23psi on stock turbo until I'm well into the 3,000's where it ramps up to 27psi.
Stock tune is similarly safe. It is moderately rich and limited to what, 22-23psi depending on altitude and weather conditions?
