Car felt responsive towards 3k rpm, but it didn’t feel like it hits full boost. When the rpm’s got higher speed climbing felt a lot more stagnant and not picking up as fast as it initially did. One weird thing is under light acceleration I hear a slight rattle between 2000-2300 rpm ( didn’t hear it when pushing pedal hard all the way so doesn’t apply to this specifically but was wondering if that can be fixed). Anyways, I feel like it can push alot more. I did a pull side by side with my friend’s stock 08 Lexus IS 350 from 4th gear and he was keeping up with me until I reached about 140km/h. So I was wondering maybe I’m not hitting full boost? I know its just baseline first version tune so let me know what I should try and watch out for when I’m driving as I’m new to custom tuning as I just upgraded my turbos. Previously using Mhd stage 2+ car also felt faster post 100km/h but for some reason I feel like right now it’s picking up as well after 100km/h (60mph). Appreciate it!
