Or if all else fails,, then a SBC kit from the fiero guys. Uses the G-282 5spd.--B&M blower anyone?  LS1 anyone?   Dammit, I want to snap my axles too like Curtis!

Jeffs chip also has much less aggressive timing above the stock 9 psi limit.  For example, the stock chips timing curve flattens out after like 9 psi or something.  So at 9psi you have lets say 10 degrees of timing, and at 10psi you have 10 deg, at 11psi you have 10 deg, and so on.  They basically stopped tuning the timing after 9 psi because no one would ever go past that (yeah, right).

Forced induction engines need to have the timing retarded as boost increases, or you will have knock, ping, etc.  Jeffs chip has all the timing above 9 psi you need.  His chip continues the timing retard past 9 psi, so at 10 psi you have 8 deg, 11 psi you have 6 deg, etc.  The numbers aren't accurate, they are just an example.  This is why Jeffs chip is a great chip.  Even if you happen to go past the 11-12 psi, the timing there will at least somewhat protect the engine.  With the stock chip, going past 9 psi is bad (if you can disable boost cutoff)...I'd be scared to go any higher than 12 psi with the stock chip at all.

And the boost cutoff I think is actually a spark cut.  The pump is not going to turn off (bad idea in any case).  If you remove fuel in a high boost situation, you could go lean long enough to damage something.  But if you remove spark, there is no combustion.  No chance to go lean.  Just my observation...

So get Jeffs chip, you will be much happier and safer than any other way.  And there is no point to running past 12 psi with the stock turbo.  There is no power increase because the turbo is working way too hard at that point to feed a fairly large engine.  For example, most ricers will use a T3 to feed a 4 cylinder engine (a T3 is way bigger than our T25).  But, our T25 is feeding a 6 cylinder engine.  You get almost no turbo lag, but you do have a ceiling of boost.  If you really want to go faster, get a T3 or something bigger, get your heads ported, larger injectors, chip....you'll be going plenty fast then.
