Nope - you shouldn't have any problems. The stg3 chip runs 100mbar more boost, and 3 degrees more
timing. The 1.4 psi more may be equivilent to ~10-15hp more alone, and the 3 degrees of timing (if you have good enough fuel quality to keep the engine from sensing knock) will give you more of an edge over stg1 - how much? I am really not sure. I also believe the MTM stg3 ecu deletes the first set of precats, so you won't throw a check engine light if you use test pipes. Let me know if it does - I can't remember...
