I've got a set of Guru chips I'll sell you. Just a few months old and include the reliaboost (but not the 3 bar fpr, which you'll also need). $199 and they are yours. Nothing wrong with them (car actually ran great on them, numbers in sig are with them), but I was troubleshooting a boost issue which actually turned out to be the AFM (found this out after I'd bought new chips).
Both Vitesse and Guru require a 3bar fpr for all their 88 Turbo S/89 Turbo chips. I can't see how any others that are worthwhile could get by with anything less (without upgrading injectors).
