Hi guys/girls just had my 2wd engine rebuilt all done proffesionaly so i know ive got a good starting point potential wise for increase in power and torque , dyno,d the engine and was all good . before it let loose 2 yrs ago by a belt coming off not snapping ,the pipe was blowing slightly and in desperate need of full setup.misfiring etc , even tho the new engine is in and im on the road these probs are still there due to basically trying to get her legal n on the road and now its the next stage. rectify the misfires n know its all correct via a prof tune/check.at the moment its driveabilty is total shit. i know it will perform better after the exhuast is sorted and im gonna buy stg 1 chip from stu plus the ignition upgrade, what kinda of driveability should i expect. in fourth at 2 grand , feed the throttle heavy n its worse thn my 1600cvh escort by miles. it is a 3 inch scorpian t3 yellows L6 k&n otherwise standard. 10psi ish. im just not happy with the lag , and im so hoping im gonna be more impressed when its tuned properly . ive gunned it a couple of times knowing i should'nt risk it really but i did lol. it goes well for what she is but low down off boost its horrid. also where the turbo joins the ex maifold , im told it will seal by the carbon deposits , as theres no gasket im curious to this. any info appreciated its blowing from there defo, sounds minor on the system somwhere too. pls god i hope i can work towards some nice response type drivin or it will ruin it for me....... i expect a bad drive with blowing pipe but its not greatly noticable to the ear , my cvh turbo blew once but still miles better low down driveability thn this. im gonna do the fan and fuel loom now b4 anymore heavy driving or runnin. also the fuel pressure test. just hope the t3 does the job for me

Change the fuel filter, seen this many times good response on boost terrible off boost, had it on mine when I got it nothing at all below 2500rpm, changed fuel filter and it pulled nicely off boost.
I would service anything that you can, misfires are usually caused by small dodgy bits, such as leads/plugs.
Unless it's new put in a new CTS as a minimum, but do airtemp sensor as well would be better, but defo CTS(coolant temp sensor), this is what determined the vast majority of the air fuel ratio.
A stage 1 chip brings a massive increase in low down off boost compared with a std set up.
It would be a good idea first to rewire the FAN/s and the fuel pump, these are notoriously crap on cossies.
At stage 1 I would use AGPR12PP8 plugs from ford, but others have thier own favourites like 071(std rst plug).
Don't take for granted that a coilpack conversion is going to cure a misfire, it won't, unless the misfire is caused by the coil, the original problem needs sorting.
A looked after cossie is capable of very high bhp before misfiring becomes a problem due to boost, a lot opt for the "group a" coil at around Ł35.
But once you have done all the basic stuff to save you money, a check is well advisable.

If it's gutless off boost, well a T3 has no lag at all relatively speaking, if it's gutless off boost... well like tabetha says, could be fuel filter. Is it noticeably misfiring at any stage? You don't seem to say for certain if it's misfiring.
Edit: ok you do say it's misfiring, when??
