i find when im below half on the petrol guage theres a noticeable difference in power n its doing my head in. does any1 else have this problem? and is there anything i could do to sort this?

 

When was the last time the car had a tune up?

 

i aint got a clue. iv only had the car for 3 weeks n its pretty standard bar a universal k & n (i doubt thats doin it much favours) and a big bore muffler. next pay check il hav the cash for a new manifold, high flow cat, cat back system and an AEM V2. wot does a "tune" consist of and is it a gd idea to get it done after iv got my new bits on? thx for the quik reply m8

 

Well, theres a big different between a "tune" and a "tune up." A tune up consists of new Plugs, wires, maybe a cap and rotor, and possibly a Sea Foam treatment. I would do this every 35,000 miles or so. Most people say 60,000 But it doesn't hurt to do it sooner

A "Tune" is when some who is experienced in working with ECU's hooks up their computer to yours, runs datalogging, and sets all of your Timing and Air/Fuel ratios to optimal settings. This is usually only done on highly modded cars, and those running Forced Induction.
