LOL good work mate, the T4 is a pretty damn nice car, and NOT to be underestimated. 190hp at stock, 150mph and 0-60 in around 7ish secs as far as i rememeber, looked into buyin one b4 the astra, as with a remap, intercooler and few bits, these bad boys knock out 270+ hp 😃 😃 😃
there are a few dedicated tuners etc in UK who love the T4 & T5 lumps, have a search on google 😃
