Default B18C4 turbo, Fast at night but slow in day?

Hey

Gopt a stocker B18c4 like ur C1, running crome pro and a borg S256. Goes really well at night in cold air but in day runs a bit shitty. I do get some heatsoak in engine bay as ud expect but wondered if there is a timing multiplier thats taking out too much when inlet gets hot etc..

Might move it into boost pipe just before the TB as this is always much cooler than my inlet manifold. Anyone else had any issues? Cqar feels very different when its cooler. AFR's in 11's in both cases, i run 99 pump fuel. Cheers Marc.

I know hondata has compensation based on air and coolant temps, I bet crome pro does too. That's most likely your problem.

If your iat is in stock location that is probly your problem. I would put it in the intercooler or the piping on the cold side
