Is it weird that my car makes 16psi of boost on a hot day, with iat's around 30-35.

But when the iat's are 25 or below it makes 12psi at an absolute stretch, seeing 8psi commonly on cold nights and 16psi on hot days.

 

Colder temps means more dense air, means more boost.... Right? 🤣

yeah, normally you make more on colder days... your tune must have allowances for protection on colder days to prevent overboost but doesn't on warmer days... only a guess, though.

Closed loop on the FG is based off IAT’s, greater the IAT greater the base D/C and target boost

 

it’s common for tuners to use the hard work ford put in basing this variable on a variety of factors and just adding a few psi to the target boost table to generate a result. 
 

It’s an ok way of doing it but more effort is required from your tuner for consistency once modified ;)

So does that mean that is it normal behaviour then?

 

I have no idea what strategy Rob uses in his tunes, all I know is he uses PCMTEC and that the dyno sheet says its tuned to 16psi, so seeing it run at 8psi had me quite confused. Checked all the IC piping cause I thought I had a boost leak 😂

 

Secondly, does that mean that with the lower boost on colder nights that its still making the same/similar power compared to what it was tuned to? It doesn't make sense in my head as to why that would be true

That's not normal I would be checking your turbo, compressor wheel and boost control. Or call the tuner to see if it was happening on the dyno or some other random weirdness. Is it a proper boost gauge or obd2 thing.

 

8psi even in closed loop
