Hi, I have a 94 Gto, on getting up to high revs its seems sluggish like there should be more power. Turbos both checked as well as all the normal things any advice?? Thanks in advance.

Do you have an after market boost gauge fitted? Check your boost you could have a leak they are so hard to detect, if your leaking on high revs boost could be leaking you will end up on wastegate boost.
Hi Dave, Yes I have an aftermarket one, what’s a wastegate boost? Thanks

About 7 psi you should boost about 9 on standard if you have increased your boost with mbc or Ebc you should be around 12 psi if no mods…have you standard car or tuned?
Its tuned but I’ve only recently bought it and the previous owner wasnt clued up. Is this something I could do my self or is it a garage job? Thanks
Need to know the tuning history really? If the last owner had no clue we could be sucking at straws tbh. Really need more info on car maybe an under bonnet pic…you got any history at all?
Yeah I can get pics of under the bonnet tomorrow I’ll put them on thanks for the help Dave and advice. Chris

High rev power loss will usually be a boost leak, ignition issue (weak spark) or fueling. Unfortunately its not very easy to diagnose any further without knowing more.
I am not going to JAE so I can help over the weekend. Try and answer the following questions and i will see if i can help:
- List of the modifications - all of them even if they seem insignificant
- What engine speed does it start to loose power?
- What is the mileage on the car and when did it last have a proper 60k service?
Reply to my comment and then i will get a notification that you have replied.
