I have been driving the car very rarely while it was on safety boost, i fixed the problem with a new detonation sensor and took it for a spin yesterday, after smiling continuously as i had my full bar of boost back :) i thought i would see how it drove through the revs and gears, i took the revs up in 2nd to about 6k and the engine sort of missed and spluttered so i changed to 3rd and had a huge amount of lag and loss of power ( so it felt ) happened, haven't revved the car up that high since but it was boosting fine at the lower revs, has anyone seen this problem before? or any ideas on what could of caused it?

 

Many Thanks

what boost controller have you got fitted? is the settings correct on it?.

it is a g reddy controller, when i bought the car it was on 70% boost i had it running on tht when it was boosting ok then after i fixed the safety boost i kept it on 60%, havent looked furthur into the setting as dont want to mess up something that i might not be able to put right.

You might have a split pipe somewhere or popped a small pipe off, have a nose around them and feel underneath them.

Also, may be worth checking the MAF connection under the nose panel.

may be overboosting and detting. what air filter have you got on?

almost deffo a pipes come off somewhere,

Check your coil pack connectors, I had 1 with the clip broken and at higher rpm it would hold back, cause the misfire but once I slowed down the bugger would be ok again

tiny dot of super glue was a good temporary fix.
