Solihull. Sounds good that mate - dont you need a CAI though?
some argue that no iot isn't. the "required" mods for stage 2+ are HPFP and downpipe with sports cat/decat. (optional mods are CAI, intercooler.) i might have been slightly generous with the pricing to be honest:
exhaust - you've got already
HPFP - £270 from W8 Performance on here
1hr labour to get it fitted (R-Tech might be able to do this for you)
£390 for the remap (from their website/a phone quote i got 2 days ago) - that includes a DSG remap if you've got DSG.
Revo is about £600 for Stage 2 when you include the VAT so it'll be about £100 more money but you'd get more power so it'd still be what i'd choose
R-Tech are on here and a lot of people have had good results with them. they're not far from you, in Hinckley. If you go down the M6 towards the M1 they're basically just before you reach the M1.
