These guys go the extra mile before they tune your car.

They bench flow injectors to determine flow rates and spray patterns.

They smoke test your motor to determine whether there are leaks in the piping system

yavuz has a degree in mechanical engineering and he has specialised his work to car tuning which makes him a pro at what he does. Over 15years experience in car tunning, he started on carbies. He is a power fc freak as well.

good service and very informative, worth paying the extra to know he has put the time into refining your machine. remember , tunning brings the whole package together, can make or break your motor. When he tells you he has tuned your car to be driven hard, you know it will last the distance.

Good luck

Cheers for the info,Yavuz has tuned my 33 before he did a top job.I have a newer engine now and feel it needs another tune to get the best out of her. Genelle.

hey mate,

I have rectified the intake pipe problem with the 3inch pipe painted black modification. Looks stock and very tidy, seems to work fine.

I have recently noticed a problem with the car and i need to take it back to get sorted out.

On occassions i get the engine light appear as a flash on the dash. This happens at 6000rpm in second and third gear. Only happens sometimes.

Second problem is that car revs out fine when not under full load. When i put the boot into it in second gear i get a slight hesitation or pause at 6000rpm and then the car continues to rev out to 7000rpm. Funny thing is that it happens when the car is warm and running for a while. It feels like it runs out of power and then it kicks in again.

i will be taking car back to be road tested when the sydney weather clears up.

Any of you boys have ideas or suggestions.

Id say this would be excessive knock causing the engine light to flash. Take it easy until you can have it sorted out would be my suggestion. It will probably only be a few load points that may need to be rectified so hopefully nothing major.

I think you might have 2 seperate issues there

1. The engine flashing light means you may need to take out 1 or 2 degrees of timing in the high load cells above 6000rpm to solve that one. I.e. engine knock as mentioned

2. The hesitation may be your coil packs. My coil packs were fine for a while after the tune but i tended to start getting a hesitation or miss around 5000rpm. I tried other Rb25 coil packs I had and coated them in silicone etc. Changed spark plugs. In the end I got some "yellow jackets" new coil packs and straight away it fixed it. They were about $380 off a guy on the forums..When you start running high boost it becomes important to have decent coil packs. At 12psi the old coils would probably still be ok. You could try gapping down your plugs from 0.8mm - if that works then you might be best off investing in the coil packs.
