my first car over 1.6 so decided to look into tuning and mod`s, i have a 2.0 hdi 406 110 and already had probs with lack of boost at times, i fitted a new vac sol and all seams better apart from turbo lag at times, almost seamed to over reving between gears. i have looked into egr removal and disconected the vac pipe from sol, dont think i will decat because of my skill and tools. i cant wait to see improved throtle responce from a remap so looking into learning about the ecu. i hope i have the brain and time to see this through

Welcome.
