Topgunz - air to air upgrade

BOLIO 671

I can't speak from experience as I don't have a A2A kit....but I can tell u that generally the Stillen tune is Junk....it's only designed to get u to a shop/dyno so that u can properly get dialed in.... I wouldn't doubt this is ur issue. The A2A kit is running more air into the system and is also designed with the MAFS post blower.....this isnt the way the Stillen set up is and the canned tune is designed for their system not A2A.

I personally had to go thru a couple tunes before my car was driveable....1st can tune started the car but was pig rich that I couldn't drive the car in any gear past 3K rpm before AFR'S hit the 9's on regular street driving....no where near 1/2 or WOT....idle was a bit rough but in the same AFR zones as you. Even after a few maps car just didn't feel right....ended up going with Seb and EcuTek...all I can say is its been the best investment I've made. I wouldn't stress about it and would just wait til the tune/dyno....that should straighten out things
