more chance of them chips doing more harm than good. you'd be better off going down the pub and spending the money on a few beers!
theres two options with tuning, either pay the money and do it properly or leave it standard.
if going down the N/a route you could get another set of pistons and have some cutouts machined into them so youve got enough valve clearance for some decent "fast road" cams. im running cat cams 109's which still retain standard oem parts in the head.
then you will either need your current ecu remapped from somone like wayne scofield or have proper standalone managment but you will also need a wiring loom to run it which for the pair will be around 1k.
then you could start to look at the fueling system and purchase a set of jenveys or colin satchells lotus tb setup. you ideally want a decent length inlet manifold not the standard short jenvey one as this can see a good amount gained in the mid range.
with the above should see 200+ for around £3000.
going further you can look at having a decent head built with solid lifters and some more lairy cams. then onto the bottom end you can fit the 88mm steel diesel crank out of a 1900 td engine, have the block bore'd out and run 88mm pistons which will give a 2139cc engine with a hefty amount of torque to boot. should see anywhere between 220-270 depending on how far you go with the head. you'll need to loose a couple of mm of the piston/rod height due to the different crank.
im running an 88mm steel crank, 87mm forge pistons with steel roads, a slightly fettled head with cat cams 109's with piper vernier pulleys, jenvey throttle bodies, maniflow race spec manifold and a 2.5 id full system on dta managment and near on 200bhp @ the wheels so nearly 230 bhp.
the standard 4 branch manifold becomes restrictive at around 220 bhp btw
it's possible to get 300 out of these engines if moneys not an option so the sky's the limit!
