TBI Powercharger + K&N Filter
My friends owns a 90 TBI A4 Firebird.I'd like to buy him a few gifts for graduation. The TBI Powercharger,I actully read an article in a magazine and still have it where it dynoed 8 HP on a S-10 (I believe it was) Anyone use these things and noticed a power increase? A K&N air filter would also be a nice addition with the powercharger.

I don't think any of us have seen any quantifiable track or dyno data to support any power gains of this thing. Do you know what his plans are for the car? You may be better off getting him some suspension parts and or simple things like fancy plug wires, or an open element.
