[QUOTE="Jam421, post: 16311241, member: 110985"] Adjustable BMR LCA's make a big difference in traction. I'd also suggest gears. A 4.10 gear set with taller MT 305x35x20's would get you in the 3.90 rear gear range. A 2.4 upper pulley would get you in the 16.5-17psi boost range. Don't forget the Metco Belt tensioner to wrap the belt around the smaller 2.4 upper. A FRPP TB is also a staple when combined with JLT 127 CAI. But when I swapped from the twin blade to KB Mono gain was 37rwhp. Lund's tune has the KB Mono Blade TB figured out in all aspects of driveability . If you're thinking TB you could make that KB jump now rather than looking for more HP later. They say bigger intake package can bump boost up slightly. Headers are not cheap but will add 20-25rwhp + knock off 1psi boost. That would be nice given you already have plans with the Corsa's. I'm running all those mods but with H-Pipe headers at very safe 16.5psi on 93 octane. [/QUOTE]
