Boost Question

[GT-FOURNZ]

hi guys just a quik question, at what rpm should i be making full boost? went for a blat today and when in second gear and at 4000rpm was only making 6 psi and then at about 4500rpm was only just making 10 . i have a gizzmo electronic boost controller set at 10.4psi. other mods are hybrid turbo, down pipe, extractors and k&n pod filter

any advice would be muchly apreciated

To be honest due to your mods it may differ but in standard form you should be hitting full boost in between 3.5k to 4k rpm...

You have to remember that different turbos has different turbo lag times... etc..

have you blocked off the turbo VSV? if you look at the actuator there are two fittings one goes to the turbo the other to the rear of the engine, cut this pipe and block off the ends. this is the most common cure.
