Caterham has finished ahead of Marussia in the constructors' championship for the past three consecutive seasons, last year snatching 10th from Marussia in the Brazilian season finale.
So far in 2013 however Caterham has yet to beat Marussia outright in qualifying, even if Pic did split Jules Bianchi and Max Chilton in Malaysia.
The Frenchman says Caterham's form over the opening two grands prix has not given him any misgivings about his switch between camps.
"I don't see things like that," Pic said when asked by AUTOSPORT whether he regretted his move.
"I had a great year with Marussia but now I am very happy to be with Caterham for this year and the future. It's not frustrating at all.
"There are some areas where we need to progress and that's it. It's our job to fix issues and make steps forward."
Pic adds that Caterham will have to wait for upgrades before they can progress as tweaking the set-up will not be sufficient.
"We have to wait a few races [for updates] but I have trust in the team so I'm sure we can have a good step forward."
"With the tyre temperature and degradation [it helps] but you cannot find one second with set-up.
"Of course we are pushing hard with set-up and tyre management to optimise these things but at this time we wait for the updates."
