Looking For A Good Garage To Sort My Baby Out....

[celicahotwheels]

I have had my baby celica convertable for around 4 half years, everything was fine untill I got the modification bug!! last year I decided to change the manifold and exhuast from top to bottom to complement my simota carbon fibre induction kit. However since then all has not been well it has been running really rough and jerky in a on of early turbo 1980's turbo manner "crap!!", I have changed the cambelt,spark plugs etc, had it rolling road tested "only 158 bhp and not the quoted 173 factory one's". All i want is my baby to run properly again when I take her out for the summer, I will get the exhuast checked again for leaks and I might replace the orginal airbox and filter to! and check the oxygen sensor also!! am i missing anything? or has anyone got any ideas of what it could be? or know any good garages in Notts or derby region who can fault find and set up toyotas properly. Thanks for reading my rant and welcoming me to your forum....cheers p.s I also have a set of adjustable shocks that I might fit anyone got any advice or comments about this since it is going on convertable?
