I've just had my R32 GTR de-catted now it's hitting 1.05 bar on full throttle. Before it was .90. The car is running induction kits, Apexi Cat-back exhaust and now the de-cat. Is this normal to go up? Also is it safe boost to run?

How can you get the boost turned down?!? The ECU has a standard hip in at the moment.

Any help would be great!

Cheers!

Best thing to do is invest in a boost controller like a Greddy profec B get it fitted and set up properly for 1bar max.

Increased boost after de-catting is normal. Some cars do it more, some less. It´s just a result of the exhaust being more free-flowing and therefore better turbo spooling and engine breathing.

If no boost controller fitted, 0.9 bar seems too high to me. You shouldn´t run the stock turbos over 1 bar. For me personally even 1 bar is too much!

But these are only my thoughts...
