Hi people had a great day out at suprapod the weekend

but it did highlight a problem with my car

 

when pulling away froms the lights i would not get away well and was always playing catch up. i was power braking to get the best pull aways i could get,

it just seemed to be when boosting all was well,but off boost was slow to pick up speed.i had noticed it before but didnt think nothing of it till went the pod and cars where getting a good 2-3 car lengths ahead then i would wind them in. what things can i check ? i get good boost from first turbo but dont really go anywhere. i actually cant get my first turbo to under 0.8 boost.

 

i have hybrids

650 injectores

aem fic

 

any ideas

Gearbox was just a thought, you say the boost pressure is okay from the first turbo, so thought it may be the delivery of the power to the wheels through the autobox.

 

Were you going up against BPU TT Supras? You will get slower response from your hybrid turbos compared to the stock ceramic turbos, which could be the simple reason why they're getting the jump on you.
