The thing is, your car would most likely have made more bhp on the second run anyway - without touching a thing. no doubt the grs made a difference, but it's really difficult to acurately say how much of a difference.

saying that im quite tempted in this offer myself, as I'd like to see the curves my car makes now anyway, so seeing it with the grs would be interesting also.

I put the GRS water to air intercooler on my GP ...........I did this because of the changes done to the head. After many days mapping the ECU we benched at 232bhp (engine)

very tempting, had one of his intercoolers in the past and it was a well made bit of kit, with excellent customer service.

where abouts are you?

nope it made 207 on the 3th run (it did go 208 but leveled out at 207) 4th run was GRS bumped up to 115 but it was the second pass on the GRS (hot run) that gave the 225! and then another run proved it wasn't just a fluke!

when i had that done the car was standard!!. Clutch, ECU, header, Manifold, Backbox, Airfilter! the ONLY mod then was a 15% Alta V2 Pulley! gotta love it when somthing sooo small makes a big difference!

Bumping an old thread but I did the same, first runs made 217bhp with 15% V2 Alta CAI and Milltek then made 227bhp (if I remember correct) with the GRS on its first and only run with it on.

I think my GTT210 gained around 10bhp from a GRS, 2 weeks later I bought one

Just fitted a GRS last week to my S which has works air filter and exhaust. No pulley upgrade, and car seems so much more lively, bigger improvement than I first thought, tempted to rolling road it to see what difference is.
